Question

each weak i receive$23 pocket money.I save all but $ 5 of it in order to buy a game.The game costs $169.How much will i still have to save after 7 weeks ?

Answer 1

If you save all but $5, you're saving $23-$5 = $18 per week. After 7 weeks, you'll have saved 7 x $18 = $126.

Since your game costs $169, after 7 weeks, you'll still have to save $169-$126 = $43.
