Final answer:
The total cost for attending the balloon fiesta with a $10 parking fee and $22 per ticket can be represented by the equation T = 10 + 22n, with T being the total cost and n being the number of tickets.
Step-by-step explanation:
The equation representing the total cost for attending the balloon fiesta, with an entry fee of $10 for parking and $22 for each ticket, can be denoted as T = 10 + 22n, where T is the total cost and n is the number of tickets purchased. This equation assumes the parking fee is a one-time charge, and the tickets are the only variable cost.
To calculate the total cost for a specific number of people, simply multiply the number of tickets by 22 and then add the $10 parking fee. For example, if 3 tickets are purchased, the total cost (T) would be calculated as T = 10 + 22(3) = $76.
