Final answer:
After paying the $2 admission fee, Tamara has $8 left for rides. Since each ride costs $0.50, she can afford to go on 16 rides.
Step-by-step explanation:
The question asks how many rides Tamara can go on with $10 at a carnival that charges a $2 admission fee and $0.50 per ride.
Firstly, we subtract the admission fee from the total amount she has:
- $10 - $2 admission fee = $8 remaining for rides.
Then, we divide the remaining amount by the cost per ride:
- $8 ÷ $0.50 per ride = 16 rides.
Therefore, the answer is that Tamara can go on 16 rides, which corresponds to option C.
