Question

Homer and Bart plan to buy one computer for 499.00$ strictly for gaming only. Games cost 49.00$ each.

Part A: Define each variable and write an algebraic expression to describe how much they will spend before sales tax, based on purchasing the computer and the number of games.

Part B: If they purchase one computer and five games, how much do they spend before sales tax?

Part C: Homer and Bart have friends. They want to purchase extra controllers. Each controller costs 24.99$. Use an algebraic expression to describe how much they spend in total (before sales tax) when they purchase one computer, and when they purchase any number or extra controllers.

Part D: What would be the total cost, before sales tax, if Homer and Bart purchase one computer four games and three extra controllers?

Answer 1

Part A: computer cost c=$499, game cost g=$49, Total Spend s. Let n be the number of games

s=$499+n•$49

Part B: using equation from part be and replace n=5 you can find s

s=499 + 5•49=744

Part C: controller cost cl=$24.99. Let m be the number of controller they wan to bye

s=499+n•49+m•24.99

Part D: use equation in part C for n=4 and m=3
