how many laptops the math department can buy if they have $6500 to spend, have already purchased 30 textbooks that cost $116 each, and each laptop costs $439. The problem can be solved by setting up the following equation: (cost of textbooks) + (cost of laptops) = $6500 (30 textbooks * $116/textbook) + (x laptops * $439/laptop) = $6500 $3480 + $439x = $6500 $439x = $3020 x = 6.87 laptops
