Question

A store pays $10 for a baseball helmet and marks the price up by 15%. What is the amount of the mark-up?

Answer 1

To find the amount of the mark-up, we can use the following steps:

1. **Determine the cost of the baseball helmet.**
The store pays $10 for the helmet.

2. **Calculate the mark-up percentage.**
The mark-up is 15%.

3. **Calculate the amount of the mark-up.**
The formula for the mark-up amount is:
\[
\text{Mark-up amount} = \text{Cost} \times \left(\frac{\text{Mark-up percentage}}{100}\right)
\]
Substituting the values we have:
\[
\text{Mark-up amount} = 10 \times \left(\frac{15}{100}\right) = 10 \times 0.15 = 1.50
\]

Thus, the amount of the mark-up is **$1.50**.
