Question

2) James spent $65 for n books. Write an expression that can be used to find the cost of

one book

Answer 1

65 ÷ n

Explanation:

If you already knew the cost of one book, you would do:

cost of 1 book x n = 65

However, you do not know the cost, so you have to do the opposite of multiplying the cost, which is dividing.
