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