Question

A store pays $86 for a gold necklace and marks the price up by 25%. What is the amount of the mark-up?

Answer 1

To find the amount of the mark-up on the gold necklace, you first need to calculate 25% of the store's cost.

1. **Calculate 25% of the cost**:
\[
\text{Mark-up} = \text{Cost} \times \frac{25}{100} = 86 \times 0.25
\]

2. **Perform the multiplication**:
\[
\text{Mark-up} = 86 \times 0.25 = 21.5
\]

So, the amount of the mark-up is **$21.50**.
