Question

Brandy wants to buy a digital camera that costs $300. Suppose she saves $15 each week. In how many weeks will she have enough money for the camera?

Answer 1

This problem can be solved using division.

Explanation:

When asking how many weeks will it take, at $15 a week, to save up $300, the question really is asking how many times does 15 go into 300.
15 into 300 is represented as a division:
`300/15`
If you are allowed a calculator this is easy. If not, we have to solve the division.
15 goes into 30 twice, and thirty goes into 300 10 times, so
`300/15=20`
