Final answer:
To calculate the total spend at the county fair including x ride tickets, use the formula T = $9 entry fee + $5 per ride ticket (T = 9 + 5x). Multiply the number of tickets x by $5 and add the $9 entry fee to find the total cost.
Step-by-step explanation:
To calculate how much you will spend to go to the county fair and purchase x ride tickets, you use the equation that includes the cost of entry and the cost of each ride ticket. The entry cost is a fixed price, while the cost of ride tickets depends on the number of tickets you want to buy.
The cost to get into the county fair is $9, and each ride ticket costs $5. If you want to buy x ride tickets, you will spend $5 times the number of tickets (x). So the total amount spent, T, can be calculated with the formula T = $9 + $5x.
For example, if you decide to purchase 3 ride tickets, the total cost T would be $9 + ($5 × 3) = $9 + $15 = $24 total to spend at the fair.
