Kim decides to download some new music. She downloaded 6 albums and 7 singles, and her total was $ 68. The next day she purchased more music from the same retailer and downloaded 2 more albums and 9 singles for a total of $36. Assuming that all albums and singles are the same price each , how much did she spend on each album and each single? Write a system of equations to represent this situation. Then solve for the solution using the elimination method.

Please help

Answer:

Singles cost 2 dollars each and albums cost 9 dollars each.

Explanation:

system of equations

6a + 7s = 68

2a + 9s = 36

6a + 7s = 68

-3(2a + 9s = 36)

7s = 68

-27s = -108

-20s = -40

s = 2

6a + 7(2) = 68

6a + 14 = 68

6a = 54

a = 9
