Final answer:
Jenna would spend $14.00 in total at the carnival, which includes the $6.5 admission fee and $7.5 for riding three times at $2.5 per ride.
Step-by-step explanation:
To calculate how much Jenna would spend at the carnival if she rides three times, we need to consider both the admission fee and the cost per ride. The admission fee to the carnival is $6.5 per person. Each ride costs $2.5. If Jenna rides three times, her total cost for the rides would be 3 rides × $2.5 per ride = $7.5. To find her total spending, we add the admission fee to the cost of the rides: $6.5 (admission) + $7.5 (3 rides) = $14.00. Therefore, Jenna would spend a total of $14.00 at the carnival.
