Answer:

Sam and Jesse can wash 70 cars in 2 days.

Step-by-step explanation:

Sam and Jesse can wash 5 cars each hour or in one hour both Sam and Jesse can wash 5 cars.

They work for 7 hours each day over 2 days. So the total number of hours that they worked is \(7\times 2\) hours.

Hence, in 14 hours Sam and Jesse can wash,

\(=14\times 5\)

\(=70\ hours\)

Therefore, working both Sam and Jesse can wash 70 cars in 2 days.
