At the beginning of summer, Mark has $200 in savings and Ryan has $350 in savings. The brothers have mowing jobs set up for the summer. Because Mark is older, he receives $20 for each mowing job and Ryan receives $15 for each mowing job. The brothers' parents pay for the fuel used to mow, so all of the money the brothers earn goes to savings. • Write two equations, one for Mark and one for Ryan, to represent the money in savings (s) based on the number of mowing jobs (j) Mark and Ryan do. • Determine the number of mowing jobs it takes for Mark to have the same amount of savings as Ryan does. Show your answer, work and/or explanation in the box.
