A 30% increase in price led the quantity supplied of pencils in a competitive market to increase from 350.00 to 380.00. What is the price elasticity of supply for pencils? Give your answer to two decimals

The formula for the price elasticity of supply (PES) is:

\[
PES = \frac{\%\ \text{change in quantity supplied}}{\%\ \text{change in price}}
\]

### Step 1: Calculate the percentage change in quantity supplied
The quantity supplied increased from 350 to 380. The percentage change in quantity supplied is calculated as:

\[
\%\ \text{change in quantity supplied} = \frac{\text{New Quantity} - \text{Old Quantity}}{\text{Old Quantity}} \times 100
\]

\[
\%\ \text{change in quantity supplied} = \frac{380 - 350}{350} \times 100 = \frac{30}{350} \times 100 \approx 8.57\%
\]

### Step 2: Calculate the percentage change in price
The price increased by 30%, so:

\[
\%\ \text{change in price} = 30\%
\]

### Step 3: Calculate the price elasticity of supply
Now, using the PES formula:

\[
PES = \frac{8.57\%}{30\%} \approx 0.29
\]

Thus, the price elasticity of supply for pencils is **0.29** (rounded to two decimals).

3. What would happen to elasticity if the increase in quantity supplied was larger?
4. How do we interpret a price elasticity of supply less than 1?
5. Can elasticity of supply ever be negative?

**Tip:** Inelastic supply means quantity supplied is relatively unresponsive to price changes.
