Jefferson stops by a fast-food restaurant for a $3.50 cheeseburger every day. If he only ate at home and eliminated this cost, how much could he save after 10 weeks? (1 point)

The cost of a cheeseburger every day for 10 weeks would be 10*7=$<<10*7=70>>70

Thus, Jefferson could save $70 if he didn't eat at the fast food restaurant. Answer: \boxed{70}.
