5. Suppose you are the manager of a music store. At the end of one week you are going over
Vaselesa [24]

Answer:

Step-by-step explanation:

x = cheaper compact disc

y = more expensive compact disc

x + y = 375.....x = 375 - y

12.95x + 14.95y = 5306.25

12.95(375 - y) + 14.95y = 5306.25

4856.25 - 12.95y + 14.95y = 5306.25

4856.25 + 2y = 5306.25

2y = 5306.25 - 4856.25

2y = 450

y = 450/2

y = 225 <==== there were 225 of the more expensive compact discs sold

x + y = 375

x + 225 = 375

x = 375 - 225

x = 150 <==== there were 150 of the cheaper compact discs sold

check...

12.95x + 14.95y = 5306.25

12.95(150) + 14.95(225) = 5306.25

1942.50 + 3363.75 = 5306.25

5306.25 = 5306.25 (correct)
