A young man spent 1/4 of his allowance on a movie. He spent 11/18 of the remainder on after-school snacks. Then from the money remaining, he spent $3.00 on a magazine, which left him 1/24 of his original allowance to put into savings. How much of his allowance did he save?

Answer 1

allowance not spent=savings
(A - 1/4 A)(1-11/18)-3=1/24 A

check my thinking.
