Question

7. Tricia and Melanie are both saving money for their summer vacations. They both

began saving at the same time. Tricia started with $10.25 and adds $5.15 to her
savings every month. Melanie did not have a starting amount but adds $10.25 to
her savings every month. Which equation could be used to determine how many
months, m, it will take before Tricia and Melanie both have saved the same
amount of money?
i

Answer 1

5.15m + 10.25 = 10.25m

It will take about 2 months for them to have the same amount of money.

Explanation:

Tricia : 5.15m + 10.25

Melanie : 10.25m

Set them equal to each other and solve for m:

5.15m + 10.25 = 10.25m

10.25 = 5.1m

2.01 = m
