y=2 is the y intercept.</span>
There are 12 inches in one foot..
so multiply 12 by 18 and you get 216 in
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
