9. 0/10 points use an algebraic approach to solve the problem. a textbook costs a bookstore $65, and the store sells it for $81.25. find the rate of profit based on the selling price. enter an exact number.

Answer

Explanation:

Step1: Calculate the profit amount

Profit = Selling price - Cost price. So, Profit = $81.25 - 65=$16.25$.

Step2: Calculate the rate of profit based on selling price

Rate of profit based on selling price = $\frac{\text{Profit}}{\text{Selling price}}\times100%$. Substitute the values: $\frac{16.25}{81.25}\times 100%$. $\frac{16.25}{81.25}\times 100%=\frac{1625}{81.25}= 20%$

Answer:

$20$
