Stells [14]

The school can charge $7.54 for each agenda book.

Step-by-step explanation:

Given,

Purchase price of 350 books = $1137.50

Profit they want to make = $1500

Total amount = 1137.50 + 1500 = $2637.50

Therefore;

The school must sell 350 books for $2637.50

Thus,

350 books = 2637.50 dollars

1 book = \frac{2637.50}{350}

1 book = $7.535

Rounding off to nearest cent

1 book = $7.54

The school can charge $7.54 for each agenda book.
