Ivan went to a store and spent 1/3 of his money on a book. He then spent 2/5 of his remaining money on a computer game. After that, he then spent 1/4 of his remaining money on a CD. Finally, he spent 1/6 of the remaining money on a candy bar. After buying the four items, he was left with $15. How much money did he have originally, that is, before he purchased the book?

x - (5x/15 + 4x/15 + 1.5x/15 + 0.75x/15) = 15

x = 60

Ivan had $60

book = $20

game = $16

CD = $6

candy bar = $3
