The senior class had a car wash to raise money for the senior trip. It cost them $35 for supplies. They washed 75 cars and charged $6 for each car.

Question

Which of the following expressions represents the money they raised for their trip?

75 · $6 - $35
$35 + 75 · $6
75 - $35 · $6
$35 - 75 · $6

Answer 1

To determine the money raised for the senior trip, we first need to calculate the total income from washing cars and then subtract the expenses for supplies.

1. Total Income: They washed 75 cars and charged $6 for each car. \[ \text{Total Income} = 75 \cdot 6 \]

2. Expenses: They spent $35 for supplies.

3. Net Money Raised: This is the total income minus the expenses. \[ \text{Money Raised} = (75 \cdot 6) - 35 \]

So the expression that represents the money they raised for their trip is: \[ 75 \cdot 6 - 35 \]

Among the choices provided, the correct expression is: 75 · $6 - $35.
