Answer:
4
Step-by-step explanation:
Fernando-
Child 1- Child 2-
2 kids- 2 kids- = 4 grandchildren for Fernando
2 kids 2 kids These are his great grandchildren, not grandchildren.
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
