Gift Card Spending Calculation

Raymond has a gift card worth $100. He decides to spend some money from it at a bookstore. If he buys three books priced at $15 each and a magazine priced at $10, how much money will he have left on his gift card?

First, calculate the total cost of the books:

Cost of books = 3 * $15 = $45

Next, add the magazine cost:

Total spent = $45 + $10 = $55

Finally, subtract the total spent from the original gift card amount:

Money left = $100 - $55
