The money that a plumber makes varies directly with the number of hours he works. If he makes $125 in 5 hours, how much does he make in 8 hours?
$200
$40
$78.12
$150
To solve this problem, we can set up a proportion.
If the plumber makes $125 in 5 hours, then his rate is $25 per hour (125/5 = 25).
Using this rate, we can calculate how much he would make in 8 hours:
$25 per hour * 8 hours = $200
Therefore, he would make $200 in 8 hours.
So the correct answer is $200.
