Answer:
2.75 hours, or 2 hours and 45 minutes
Step-by-step explanation:
Subtract the cost of materials from the bill, 134-46=88.
Then, for every hour, he charges 32, so divide the difference by 32, 88/32.
Find the proportional relationship in a unit rate.
x:y
Put in x and y.
60:25
Divide both sides by 5.
12:5
So, every 5 units of y, there are 12 units of x.
Put the new y into proportion.
x:30
There are 5 extra units of y.
All you need to do is add 12 to the previous x.
60+12= 72
x=72
I hope this helps!
