Rick spent $3000 of his salary on furniture and 1/5 of his remaining salary on shoes. If he had 2/5 of his salary left in the end, how much was his salary?

Answer 1

Let x = salary
Let (x-3000)/5 = cost of shoes
Therefore, total salary minus his costs is the 2/5 of his salary left:
x - 3000 - (x-3000)/5 = (2/5)x
[ x - 3000 - (x-3000)/5 = (2/5)x ] * 5
5x - 15000 - x + 3000 = 2x
2x - 12000 = 0
2x = 12000
x = 6000
