Sam and Jesse can wash 5 cars each hour. They work for 7 hours each day over 2 days. How many cars did Sam and fesse wash?

If you'd like to know how to solve it;

You must take the time each day (7 hours) and the amount of cars (5 cars) and multiply. This should give you 35 cars. Then all you would need to do is add another 35 (because there's 2 days) and you have your answer.

7*5+35 = 70

or

(7*5) 2 = 70
