Answer 1

116

Explanation:

You first need to find out how much the trip will cost in total.

• There are 12 students, and the tickets cost $45, so you multiply 12 by 45 and get $540
• Transportation and meals also costs money. Multiply 12 students by $100 and get $1200.
• Finally add up those two expensises to get $1740.

The last step is to divide the cost of the trip by the profit of each car ($15) to find how many cars need to be washed.

• 1740÷ 15 = 116
• 116 cars need to be washed
