What is an economics solver?

An economics solver works through econ problems and explains the model behind them. QuizeGpt is an AI economics solver that names the idea a question tests, shows which curve moves and why, and works every formula step by step. You learn the economics, not just the answer.

  • Type a question, paste it, or snap a picture of a graph or table.
  • Get a clear answer with the formula, the numbers and the graph explained.
  • Ask a follow-up if something doesn't make sense.

What the economics solver can help with

From supply and demand to monetary policy, here's what QuizeGpt covers in micro and macro, and how it explains each topic.

Economics topicWhat you get
Supply and demandEquilibrium price and quantity, shifts, surpluses and shortages.
ElasticityPrice, income and cross elasticity, and what elastic or inelastic means.
Consumer and producer surplusThe triangles on the graph, worked out step by step.
Costs and profitMarginal cost and revenue, and where profit is highest (MR = MC).
Market structuresPerfect competition, monopoly, oligopoly and game theory.
GDP and growthGDP = C + I + G + (X − M), real vs nominal, and the GDP deflator.
Inflation and unemploymentCPI, inflation rates, and the unemployment rate, with the formulas.
Fiscal and monetary policyAD/AS shifts, the multiplier, interest rates and the money supply.
Trade and opportunity costPPF graphs, comparative advantage and gains from trade.

Economics solved step by step: examples

This is what you get. Each step shows the formula and what it means.

Elasticity

Price rises from $10 to $11, and quantity demanded falls from 100 to 80. Is demand elastic?

  1. Percent change in quantity: (80 − 100) ÷ 100 = −20%.
  2. Percent change in price: (11 − 10) ÷ 10 = +10%.
  3. Elasticity = −20% ÷ 10% = −2. Its size, 2, is more than 1, so demand is elastic.

Answer: Yes, elastic (|E| = 2)

Inflation

The CPI goes from 250 to 260 in one year. What is the inflation rate?

  1. Inflation rate = (new CPI − old CPI) ÷ old CPI.
  2. (260 − 250) ÷ 250 = 10 ÷ 250.
  3. 10 ÷ 250 = 0.04, which is 4%.

Answer: 4%

Multiplier

The MPC is 0.8. The government spends $10 billion more. How much can GDP rise?

  1. Spending multiplier = 1 ÷ (1 − MPC) = 1 ÷ 0.2 = 5.
  2. Each dollar of new spending becomes someone else's income, again and again.
  3. Change in GDP = 5 × $10 billion = $50 billion.

Answer: Up to $50 billion

Opportunity cost

In one hour, Ana can bake 4 cakes or 2 pies. What is her opportunity cost of 1 pie?

  1. Opportunity cost is what you give up to make something.
  2. Making 2 pies costs Ana 4 cakes.
  3. So 1 pie costs 4 ÷ 2 = 2 cakes.

Answer: 2 cakes

Pick a sample question, then drag a box over it to snap it, just like the Chrome extension does on your homework page.

Equilibrium price

Qd = 50 − P and Qs = 10 + P. What is the equilibrium price?

  • $20
  • $30
  • $10
  • $40
QuizeGptSolved

Drag a box over the question, just like in the extension. On a phone, tap it. Or press Snap & solve.

  1. At equilibrium, Qd = Qs: 50 − P = 10 + P.
  2. Add P to both sides and subtract 10: 40 = 2P.
  3. So P = $20, and Q = 50 − 20 = 30.
✓ 3x Verified $20 $30 is the equilibrium quantity, not the price. $10 and $40 come from adding or subtracting wrong.

Sample questions with saved answers. The extension works on any question you snap. Want the full tour? Try the interactive demo.

Supply and demand: what happens when demand rises

Most econ questions start here. When something makes people want more of a good at every price, the demand curve shifts right. Watch the market find its new equilibrium.

Demand ↑ (D1 → D2) Price ↑ Quantity ↑
  1. Start at E1, where supply (S) meets the first demand curve (D1).
  2. Demand rises, so the whole curve moves right, from D1 to D2.
  3. The new equilibrium E2 is higher and further right: price and quantity both go up.

What happens to price and quantity?

What happensCurvePriceQuantity
Demand rises (more buyers, higher income, a trend)Demand shifts right↑↑
Demand falls (fewer buyers, a cheaper substitute)Demand shifts left↓↓
Supply rises (better technology, cheaper inputs)Supply shifts right↓↑
Supply falls (a new tax, costlier inputs, a bad harvest)Supply shifts left↑↓

A price change alone doesn't shift the curve. It moves you along it: that's a change in quantity demanded, not a change in demand.

Supply and demand calculator, and the formulas you'll use

Give QuizeGpt the demand and supply equations, and it works like an equilibrium calculator, but it shows every step. Here are the formulas behind most econ homework.

What you needFormula
EquilibriumSet Qd = Qs, solve for P, then plug P back in for Q
Price elasticity of demand% change in quantity demanded ÷ % change in price
GDP (spending approach)C + I + G + (X − M)
Inflation rate(CPI this year − CPI last year) ÷ CPI last year × 100
Unemployment rateUnemployed ÷ labor force × 100
Spending multiplier1 ÷ (1 − MPC)
Real GDPNominal GDP ÷ GDP deflator × 100
ProfitTotal revenue − total cost (highest where MR = MC)

How to solve economics problems, step by step

Whether you use a solver or not, this five-step method works on most econ questions.

  1. Step 1

    Name the model

    Is it supply and demand, elasticity, GDP or the multiplier?

  2. Step 2

    Draw it

    Sketch the graph, even for number questions. It shows what should happen.

  3. Step 3

    Write the formula

    Then plug in the numbers, keeping $, % and units.

  4. Step 4

    Say what moves

    Which curve shifts, which way, and what happens to price and quantity?

  5. Step 5

    Check the direction

    Does the answer make sense? Higher demand shouldn't lower the price.

How to check an economics answer

Any tool can slip, and so can you. These quick checks catch most econ mistakes.

↗️

Does the direction fit?

More demand should raise the price. More supply should lower it.

🔁

Plug it back in

Put your equilibrium price into both equations. Qd and Qs should match.

%

Units and percents

Is it dollars, a percent, or a number of goods? Label every answer.

Common economics mistakes to avoid

Demand vs quantity demanded

A price change moves along the curve. Only other things, like income, shift it.

Nominal vs real

Nominal uses today's prices. Real takes inflation out. Check which one the question wants.

Counting twice in GDP

GDP counts only final goods. The flour in a loaf of bread isn't counted again.

Elasticity signs

Price elasticity of demand is usually negative. Compare its size to 1 to call it elastic or not.
