Final answer:
To calculate the percent profit made on a pair of pants, subtract the cost price from the selling price and express it as a percentage of the cost price.
Step-by-step explanation:
To find the percent profit made on the pair of pants, you need to calculate the difference between the selling price and the cost price, and then express it as a percentage of the cost price.
Cost price: P²⁵⁰
Selling price: P³⁵⁰
Profit = Selling price - Cost price = P³⁵⁰ - P²⁵⁰ = P¹⁰⁰
Percent profit = (Profit / Cost price) * 100% = (P¹⁰⁰ / P²⁵⁰) * 100%
Simplifying the expression, we get:
Percent profit = 40%.
