Answer:
The cost of one Icee is $6.5
Explanation:
Let x represent the cost of each Icee. Since each ticket cost $20 and a total of 2 tickets was purchased, hence the total cost of tickets is:
Cost of tickets = 2 * $20 = $40
They then purchased an Icee afterwards, hence the total money spent is:
Total money spent = 40 + x
After using a gift card of $10, the total purchase was $36.50, hence:
Total purchase = 40 + x - gift card
36.5 = 40 + x - 10
x + 40 = 46.5
x = $6.5
