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
