Tom spent $1440 of his salary on food, gave 40% of the remaining money to his parents and saved the rest. He saved 15% of his salary every month.

(a) What percentage of his salary did he give to his parents?
(b) What was Tom's monthly salary?

1 answer

Tom's salary ---- x
amount left after buying food = x - 1440
amount left after giving 40% to parents = .6(x - 1440)

Problem:
Did he give 40% of the "remaining money" to his parents
before he put away his 15% for saving or after?
