Mr James spent 5/8 of his salary and gave 1/3 of the remainder to his mother. If he had $300 left, how much did he spend?

300/2 = 150

150*5 = 750

Hey Guest, I'm really curious how that worked...can you explain how you knew to do that??

1500

Let his salary = S

After he spends 5/8 of his salary, he has (3/8 )S left

After he gives (1/3) of this to his mother he has (3/8)(2/3)S = (1/4)S left

And this = $300

So

(1/4)S = 300 multiply both sides by 4

S = $1200

And he spent (5/8) of this = (5/8)(1200) = $750
