Answer :
Answer:
It was used as the multiplier because the 5 represents the hours she's worked. If she uses the 1/5 graph she will find the unit rate of each time she gets paid an hour.
Step-by-step explanation:
The problem can be solved by knowing the concept of work and time.
Given to us,
Lin is paid $90 for 5 hours of work,
amount earned/time worked
-----------------------------
I 90 I 5 I 1/5
I 18 I 1 I
I 144 I 8 I
Part A: how much she would be paid at this rate for 8 hours of work?
For 5 hours Lin was paid =$90
For 1 hour Lin will be paid = [tex]\dfrac{Amount\ paid}{Time\ for\ which\ Lin\ was\ Paid} = \dfrac{90}{5} =[/tex] $18/hour.
For 8 hours Lin will be paid = Amount paid for 1 hour x Number of hours
= $18 x 8
= $144
Hence, Lin will be paid $144 for 8 hours of work.
Part B: the number 1/5 used as a multiplier,
It is used as a multiplier to get amount paid per hour for the amount of $90 which was paid for 5 hours of work.
