Problema Solution
Ben spent 1/4 of his allowance on a movie. He spent 11/18 of the remainder at Starbucks. Then, from the money remaining, he spent $9 on magazines, which left him 1/24 of his original allowance. How much money was left?
Answer provided by our tutors
We assume he has X at first, so the equation is
(1- 11/18)*(X - 1/4*X) - 9 = 1/24 * X
We solve it
X = 36
So the money left = 1/24 * $36 = $1.5
