Amount John have left

John  earned $45.90 during the summer break.

He used 1 / 6 of the money to buy trading card. Then he used the following amount to buy the trading card.

  • 1 / 6 × 45.90 = $7.65

Then, he used 3/5 of the remaining amount to buy a sketchbook, and also spends $4.50. Therefore, the total he spends can be computed as follows:

  • 3 / 5 × (45.90 - 7.65) + 4.50 = 22.95 + 4.50 = $27.45

So, He spent

  • $7.65 on trading cards
  • $22.95 on sketch book
  • $4.50 on comic book.

The amount he has left = 45.90 - 7.65 - 22.95 - 4.50 = $10.8
