Mandy bought 5 computer games and a carrying case for a total of $155. The carrying case cost $15. Each computer game cost the same amount. What is the cost of each computer game?

Set up an algebraic equation to find the cost of each game. 5x+15=155. x is the cost of each game multiplied by 5 (total amount of games). 15 is the cost or the carrier. 155 is the total cost. Now you solve: 5x+15=155, 5x=140, x=28. The cost of each game is $28. Check: 5 (28) + 15=155
