# Price Elasticity of Demand for Paint: Supply and demand from a microeconomics perspective

Suppose you are a painter, and the price of a gallon of paint increases from $3.00 a gallon to $3.50 a gallon. Your usage of paint drops from 35 gallons a month to 20 gallons a month. Perform the following:

1. Compute the price elasticity of demand for paint and show your calculations.

2. Decide whether the demand for paint is elastic, unitary elastic, or inelastic.

3. Explain your reasoning and interpret your results.

#### Solution Preview

The formula for Price Elasticity of Demand (PeD) is:

PeD = (Percentage change in Demand) / (Percentage change in Price)

Where:

Percentage change in Demand= (Current demand - Old demand/ (Old demand)

Percentage change in Price = (Current price - Old Price) / (Old price)

Computation

Given:

Old price of paint: $3

New price: $3.50

Old demand for paint: 35 gallons

New demand for paint: 20 gallons

Substituting the values in the ...
