Solve the problem.

The band sponsored a car wash. During the first session, the students earned $78. During the afternoon session, they earned $54. That evening when people were on their way home from work, the students earned $81. If the band charged a whole dollar amount for each car, what was the charge per car?

Select the correct answer.

Question 4 options:

3 dollars

2 dollars

4 dollars

To find the charge per car, we need to find the total amount earned and divide it by the number of cars washed.

The total amount earned is $78 + $54 + $81 = $213.

Since the band charged a whole dollar amount per car, the charge per car would be the nearest whole number to $213.

Rounding $213 to the nearest whole number, we get $213 as the charge per car.

Therefore, the correct answer is not listed.

To solve this problem, we need to find the charge per car.

First, let's add up the total earnings from all three sessions:
$78 + $54 + $81 = $213

Since we know that the band charged a whole dollar amount for each car, the charge per car can be found by dividing the total earnings by the number of cars washed.

To find the charge per car, we need to determine how many cars were washed in total. Unfortunately, we don't have that information, so we cannot calculate the charge per car. Therefore, the answer cannot be determined based on the information provided.

To solve this problem, we can use addition and then divide to find the charge per car.

First, let's add up the earnings from each session: $78 + $54 + $81 = $213.

Since we know that a whole dollar amount was charged for each car, we need to find a number that evenly divides $213.

Let's start by trying $1 as the charge per car: $1 * X = $213, where X represents the number of cars. However, we can see that $1 is too small because it doesn't evenly divide $213.

Next, let's try $2 as the charge per car: $2 * X = $213. Dividing both sides by $2 gives us X = $213 / $2 = 106.5. But we know that the number of cars cannot be a decimal, so $2 is also too small.

Finally, let's try $3 as the charge per car: $3 * X = $213. Dividing both sides by $3 gives us X = $213 / $3 = 71. This gives us a whole number of cars, so $3 is the correct charge per car.

Therefore, the answer is: 3 dollars.
