Jonathan wants to save up enough money so that he can buy a new sports equipment set. The complete set costs $50. Jonathan has $15 he saved from his birthday. In order to make more money, he plans to wash his neighbors windows. He plans to charge $3 per window he washes, and any extra money he makes beyond $50 he can use to buy the additional accessories that go with the sports set. Write and solve an inequality that represents the number of windows Jonathan can wash in order to save at least the minimum about what he needs to buy the boxed set. Graph the solutions on the number line. What is a realistic number of windows for Jonathan to wash? How would that be reflected in the graph?
