Final answer:
The algebraic expression to determine the total cost for one computer, g number of games, and c number of controllers is 299.00 + 49.99g + 19.99c.
Step-by-step explanation:
Giovanni is buying a computer, games, and controllers, where g is the number of games and c is the number of controllers. To determine the total amount paid for one computer, any given number of games, and any given number of controllers we can write the algebraic expression as follows:
Total Cost = cost of computer + (cost of one game × number of games) + (cost of one controller × number of controllers)
Therefore, the algebraic expression is:
299.00 + 49.99g + 19.99c
This expression can be used to calculate the total cost by substituting the values of g and c for the number of games and controllers purchased respectively.
