Buy one get one free on earbuds, retail price is $25 each. I sell the earbuds for $17 each.

What is my cost for each pair of earbuds?

What is my profit for each pair of earbuds?

How much is the buyer saving off of retail?

So if you bought 2 earbuds, you pay 25 (buy one get one free)

then you sell each for 17

so 17*2=34

spent 25

earned-spent=profit

34-25=9

he saves $25 since he doesn't have to pay for the second pair

cost for each pair is $25

profit for each pair is $9

he saves $25 off retail per pair
