Question

Itunes sells some songs for $059 and some for $0.99. Jim buys 35 songs for $25.45 how many cost $0.59 and how many cost $0.99

Answer 1

Your equation is 0.59x + 0.99(35-x) = 25.45

 

The total number of songs bought was 35 so a certain number are bought at 0.59 and is represented by x and the balance are 35 less that number, so 35 - x and cost 0.99

 

Now solve

 

0.59x + 34.65 - 0.99x = 25.45

-0.4x + 34.65             = 25.45

-0.4x                         = -9.2

x                               = 23

 

So 23 songs were bought at 0.59 and 35-23 = 12 songs bought at 0.99

 

All the best
