the cost of each pair of shoes before discount is $56
Step-by-step explanation:
Let the cost of each pair of pants = y
Amount to be discounted per pair = $16
Discount on each pair = y - 16
For 4 pairs = 4(y - 16)
Amount paid before tax = $160
This means this is cost of the 4 pairs after discount has been deducted.
4(y - 16) = 160
4y - 64 = 160
4y = 160 + 64
4y = 224
4y/4 = 224/4
y = 56
Hence, the cost of each pair of shoes before discount is $56
