We will call:
M=Mari
J=Jen
Initial equations:
M=2J
M+J=480
(the fact that they work 20 hours a week is not needed in this problem information)
Plug in:
2J+J=480
3J=480
J=160
Jen makes $160 a week.
Therefore:
M=2J
M=2(160)
M=320
Mari makes $320 per week
Jen makes $160 per week
If 8000 dollars multiplied by 2% is 160 dollars and 160 dollars multiplied by 3 years gives you the answer of 480 dollars
Answer is 9r
