D) 30%

Answer 1

$71/$51 = about 1.392 = about 39% increase

The correct answer is C.

Answer 2

To find the percent increase of the shoe prices, calculate the difference in price, divide by the original price, and convert to percentage. The price increases from $51 to $71, which is a 39% increase after rounding.

Step-by-step explanation:

To calculate the percentage increase of the price of the shoes from $51 to $71, we follow these steps:

1. Find the difference in price: $71 - $51 = $20.
2. Divide this difference by the original price: $20 ÷ $51 ≈ 0.3922.
3. Convert this to a percentage by multiplying by 100: 0.3922 × 100 ≈ 39.22%.

Rounding to the nearest percent, the price increase is approximately 39%.
