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
B=7
3(b-4)+5b=44
3b-12+5b=44
8b=44+12
8b=56
b=7
It be a 3/4 possibility that it won’t be green
