Question

Joe purchased 15 pairs of socks from an online vendor and received a 20% discount. shipping cost $4.99. how much does each pair of socks cost, without the discount, if joe spent a total of $79.99

Answer 1

Take the total: $79.99

Subtract the shipping cost: $4.99 ($75)

Divide that by the number of socks: 75/15
=$5 per sock with the discount

Take the discount of 20% and multiply that by the sock price $5 - 5 x .20 = 1

Add that to the sock price: 1 + 5 = 6

$6 per sock without the discount is your answer
