Tracy is saving to buy a new guitar that costs $253.77 (including tax). tracy has saved $136.27, and she can save $23.50 each week.
how many more weeks will it take her to save enough money?

2 weeks
5 weeks
7 weeks
10 weeks

Subtract how much she has saved already from the total cost:

253.77 - 136.27 = 117.50

She needs $117.50 more.

Now divide that by the savings per week to find the number of weeks:

117.50 / 23.50 = 5 weeks.

5 weeks
