Question

a computer store bought a program at a cost of $10 and sold it at a selling price of $13. find the percent markup. the percent markup is \\(\square\\)% (round to the nearest whole number as needed)

Explanation:

Step1: Find the markup amount

The cost price (CP) is $10 and the selling price (SP) is $13. The markup amount (M) is \( SP - CP \).
\( M = 13 - 10 = 3 \)

Step2: Calculate the percent markup

The formula for percent markup is \( \text{Percent Markup} = \frac{M}{CP} \times 100 \).
Substitute \( M = 3 \) and \( CP = 10 \) into the formula:
\( \text{Percent Markup} = \frac{3}{10} \times 100 = 30 \)

Answer:

30
