Question

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6500 to spend and purchase 30 textbooks, how many laptops can they buy?

Answer 1

Answer:

6 laptops.

Step-by-step explanation:

$6500 is the budget. If each textbook costs $116, and 30 textbooks are needed, you multiply.

116 x 30 = 3480.

3480 was spent on the textbooks, and the rest needs to go into laptops.

6500 - 3480 = 3020.

Now to find out how many laptops can be bought with the remaining money, divide.

3020 / 439 = 6.88 (You can't buy a portion of a laptop, so you have to take the biggest whole number, which is 6).
