Final answer:
To calculate Matt's total cost for the night, the equation is C = 25 + 3n, where C represents the total cost and n is the number of concession items purchased.
Step-by-step explanation:
In order to determine Matt's total cost for the night when he goes to see a hockey game, we need to write an equation that includes both the fixed cost of his ticket and the variable cost of any food or drink items he might purchase. The ticket cost is a fixed amount, $25, and each food or drink item costs an additional $3.
An equation to represent Matt's total cost (C) can be written as:
C = 25 + 3n
where n represents the number of food or drink items Matt buys.
For example, if Matt buys 4 items from the concession, his total cost would be calculated as:
C = 25 + 3(4) = 25 + 12 = $37
This equation allows us to calculate Matt's expenses for any number of concession items he chooses to buy.
