Jessica makes $36 less than Kimmie  

Step-by-step explanation:

x -----> amount paid to Jessica

y  ----> amount paid to Lauren

z ----> amount paid to Kimmie

we know that

------> equation A

-----> equation B

-----> equation C

substitute equation B and equation C in equation A and solve for y

Find the value of x

Find the value of z

therefore

The  amount paid to Jessica was $24

The amount paid to Lauren was $36

The amount paid to Kimmie was $60

To find out how much less Jessica did than Kimmie, subtract the amount paid to Jessica from the amount paid to Kimmie.

therefore

Jessica makes $36 less than Kimmie
