Together Paul and Jack earned $72 washing cars. Jack washed twice as many cars as Paul. If Paul washed 3 cars, how much did they charge to wash each car?
p = 3, so j = 6
So they got $72 for 9 cars.
now just finish it off.
so 8 dollar per car
First, let's find out how many cars Jack washed. We know that Jack washed twice as many cars as Paul, who washed 3 cars.
Jack washed 3 * 2 = <<3*2=6>>6 cars.
Now, let's determine the total amount earned from each car washed.
The total earnings for washing cars are $72, and the total number of cars washed by Paul and Jack is:
3 + 6 = 9 cars.
To find out how much they charged to wash each car, we divide the total earnings by the total number of cars washed:
$72 / 9 cars = $<<72/9=8>>8 per car.
Therefore, they charged $8 to wash each car.
To find out how much they charged to wash each car, we can divide the total amount earned by the number of cars washed.
In this scenario, Jack washed twice as many cars as Paul, who washed 3 cars. Thus, Jack washed 3 * 2 = 6 cars.
Now, let's calculate the amount they charged per car.
The total amount earned was $72, and together they washed 3 + 6 = 9 cars.
Dividing the total amount earned ($72) by the number of cars washed (9), we'll get $8.
Therefore, they charged $8 to wash each car.
