The final cost of the computer can be calculated as ...
(original cost)*(1 -0.20)*(1 +0.04)
= $750*0.80*1.04 = $624.00
The ending balance on Hakim's bank account is
$700 +700*.05 = $735.00
The amount remaining after Hakim pays for the computer is
$735.00 -624.00 = $111.00
11. 7, or -1
you are setting it so it's equal to 0
There is no work being done. You just need to set one or both equations up so it equals 0
0(x) will always be 0
This is easy basically what you're going to do is that you have 5 friend and you only have 2 bags of Trail Mix that would make it 2 / 5
