Answer:
$16.2
Step-by-step explanation:
15 x .08 [wonder how i got .08? 8% = 0.8]
= 1.2
here's where most people mess up, they usually forget to add the tax to the original cost.
15 + 1.2=
$16.2
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
