Answer :

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
