Answer:
Tanya: $ 2
Tony: $ 1.5
Step-by-step explanation:
Part a)
Number of games that Tanya bought = 3
Cost of each game that Tanya bought = x
Since, the cost for each game is x, the cost for 3 games would be 3x. So we can write:
Total cost of Tanya's items = 3x
Part b)
Number of games that Tony bought = 4
Each game that tony bought was $0.5 less in cost that what Tanya paid for each game. This means,
Cost of each game that Tony bought = x - 0.5
Since, the cost of each game is (x - 0.5), the cost for 4 games would be 4(x - 5). Thus,
Total cost of Tony's items = 4(x - 0.5)
Part c, d and e)
Since, both Tanya and Tony paid the same amount for their purchases, we can write:
Total cost of Tanya's items = Total cost of Tony's items
Using the values from previous parts, we get:
3x = 4(x - 0.5)
3x = 4x - 2
2 = 4x - 3x
x = 2
Since, x represents the cost of each item that Tanya paid, we can conclude that the cost of each game of Tanya was $ 2 and cost of each game of Tony was $ 1.5
