The total cost for 10 pairs of headphones, including shipping was $125. The shipping charge was $15. What was the cost of each pair of headphones? Write and an equation and find the solution.

Step-by-step explanation:

given data

chipping charge= $15

cost of 10 pair= $125

le the cost of 1 pair be x

given that 10 pairs cost $125

then 1 would cost x

cross multiply we have

10x=$125

x= 125/10

x=$12.5

therefore the equation for the solution is

let y be the total cost

y=15+12.5x

nswer: a   y-axis

step-by-step explanation:

just sum

10 + 10 = 20
