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 Jesse wash?

The answer is 70.

Step-by-step explanation:

Ratio of cars per hour is 5:1

For every hour, they wash five cars. Multiply 5 times 7. That equals 35. That's 35 cars per day. Now they're asking for 2 days. Multiply 35 by 2 (because of the 2 days) and you get 70 cars.
