babysits for 7 hours. You may solve with any method but you must show your work.

Explanation:

First, you want to find the unit rate, or how much Han earns per hour

You can do this by setting up an equation

x= amount earned per hour

4x= 33 Initial equation

4x/4 = 33/4 Isolating the variable

x = 33/4 = 8 1/4 = 8.25 The unit rate

Now you want to set up a new equation to find out how much he makes for 7 hours

x= amount earned per hour

y = total amount earned

y = 7x Initial equation

y = 7 ( 8.25) Substitution

y = 57.75 The answer

Han earns $57.75 for every 7 hours

Checking the answer....

y = 7x

57.75 = 7x Substitute y instead

57.75/7 = 7x/7

8.25 = x

Your answer should be correct

Hope this helps!!!

First you do $33.00/4 to get $8.25. Take the 8.25 and multiply it by 7 to get $57.75
