Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2

If 12 dozen were bought for $90 that means each CD was bought at the price of $0.66
If he sold all 60 of the CD's for 5 for $12, he'd make $144.
Subtract the income by the original buying price to find his profit. $144 - $90
The peddler made $54 profit.
