Final answer:
To calculate the total cost for Sanjay at the carnival, multiply the cost per ride by the number of rides and add the entrance fee. The calculation is $0.50 per ride times 6 rides plus an $8 entrance fee, totaling $11.
Step-by-step explanation:
The student asked how much Sanjay will spend in total at a carnival if the entrance fee is $8 and each ride costs $0.50, and he rides 6 rides.
To find the total cost, we need to calculate the cost of the rides and add it to the entrance fee.
The cost of 6 rides at $0.50 each will be 6 rides × $0.50 per ride = $3.00 for rides.
The entrance fee is a fixed cost of $8.00.
Therefore, the total cost will be the sum of the cost of the rides plus the entrance fee: $3.00 + $8.00 = $11.00.
So, the correct answer is b. $11 dollars.
