Henry spent 1/5 of his salary and an additional $500 of his salary on a PS4

console.  He then spent 3/4 of his remaining money and an additional $50 of

his salary on 8 PS$ game discs.  In the end, he had $10 left.

a) How much did the 8 PS4 game discs cost?

b) How much was Henry's salary

s = salary

 

1/5 s + 500      Spent on PS4      what he has left:   s - (1/5s + 500) =  4/5 s - 500

 

Spends 50 +  3/4 of what is left

  3/4 ( 4/5 s - 500)  + 50 

 12/20 s -325

                 now he has    4/5 s - 500    - (  12/20 s -325)

                                          -4/20 s -175  

  and this = 10

 

-4/20 s - 175 = 10 

   s = 925

             You should be able to find part A
