Question

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

Answer 1

So first, just calculate how much more she needs to save to get the guitar.

253.77 - 136.27 = 117.5

And now just find how many weeks she needs to save up for.

117.5 / 23.5 = 5

So she needs to save up for 5 more weeks.

Answer 2

Option B., 5 weeks

Explanation:

Tracy is saving to buy a new guitar that costs = $253.77

Tracy has already saved = $136.27

Now she needs = 253.77 - 136.27

= $117.50

She can save each week = $23.50

Tracy will take weeks to save enough money =
`(117.50)/(23.50)`

= 5 weeks

Option B. 5 weeks is the answer.
