Question 911388
Total amount of sales: $88000
x+y=88000,
Total commission for the two products is: $4880
0.06*x+0.04*y=4880
x=88000-y
Substitute for x
0.06*(88000-y)+0.04*y=4880
Multiply out
5280-0.06*y+0.04*y=4880
Combine like terms.
-0.02*y=-400
Isolate y
y=$   20000.00 at 4%
x=88000-y
Calculate x
x=$   68000.00 at 6%
Check
0.06*68000+0.04*20000=4880
4080+800=4880
4880=4880
If this statement is TRUE and neither x nor y  is negative then all is well
