Answer:
Part A: 7.25h= total amount earned
Part B: 5 hours
Step-by-step explanation:
Part A:
So we know that he gets paid $7.25 an hour, so now we just need to set up an equation. For every hour he works, he gets $7.25. If h= hours, then it would be expressed like this:
7.25h= amount of total dollars he will get paid
To check this, you can plug in random values, 3 for instance:
7.25 (3)= $21.75 so he would get paid $21.75 for painting fences for 3 hours.
Part B:
If his first customer paid him $36.25, and he gets paid $7.25 an hour, you would divide the 2 values to find how much he earns per hour.
It would be set up like this:
36.25/ 7.25= 5
So he worked 5 hours. We know the first equation can be used to calculate how much he earns in total, so we can just plug it in to check:
7.25(5)= $36.25
That works, so you're all good to go! Hope this helps :)
