Fred was given some pocket money. He spent 1/3 of his money to buy games and saved 2/3 of the remainder. He used the rest of the money on food. If he spent $120 altogether, how much did he save?

Answer 1

x to start
1/3 x spent on games, leaving 2/3 x
4/9 x saved, leaving 2/9 x

x/3 + 2/9 x = 120
5/9 x = 120

4/9 x = 96 was saved
