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
