Answer:
8 weeks
Step-by-step explanation:
Given Valerie want's to buy a backpack which costs $57.65
Also given that she saves $7.25 a week
Let the number of weeks she saves the money be x
For her to buy the backpack the following inequality should be satisfied
amount saved > cost of the item
The amount saved =
7.25x > 57.65
x > 7.95
Since x is an integer we have x = 8
Therefore she has to save 8 weeks to buy the item
