Ricia 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 $9.25 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? Group of answer choices

10.25m – 5.15 = 9.25m

10.25m + 5.15 = 9.25m

9.25m + 10.25 = 5.15m

5.15m + 10.25 = 9.25m
