Answer:

116

Step-by-step 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
