Step-by-step explanation:

Answer 2

Answer:

The number of cars must they wash in order to have enough money to pay for the trip is 40.

Step-by-step explanation:

The total amount of money required for the four student government officers to go to the state convention is:

$Amount\ needed=\ 120+\ 355+(\ 456\times4)=\ 655$

The amount saved for the convention in the student government savings account is $495.

The additional amount required is:

Additional amount = Amount Required - Amount Saved

                               = $655 - $495

                               = $160

The four students decided to earn the additional amount by washing cars.

They charge $4 for each car wash.

Compute the number of car wash the students must do is:

$Number\ of\ car\ wash=\frac{160}{4} =40$

Thus, the number of cars must they wash in order to have enough money to pay for the trip is 40.
