Q. 66. Katie and her friend went to the county fair. They each brought a $20.00 \$ 20.00 bill. The admission fee was $4.00 \$ 4.00 per person. Ride tickets cost 5050 cents each. If each ride required two tickets per person, how many rides was each girl able to go on?\newline(A) 1616 rides\newline(B) 3232 rides\newline(C) 88 rides\newline(D) 2020 rides
  1. Subtract Admission Fee: question_prompt: How many rides can each girl go on at the county fair after paying the admission fee with a $20\$20 bill?\newline Step 11: Subtract the admission fee from the $20\$20 to find out how much money each girl has left for rides.\newline$20.00−$4.00=$16.00\$20.00 - \$4.00 = \$16.00 left for rides.
  2. Calculate Ride Cost: Step 22: Calculate the cost of one ride by multiplying the cost of one ticket by the number of tickets needed per ride.$0.50\$0.50 per ticket ∗* 22 tickets per ride = $1.00\$1.00 per ride.
  3. Calculate Number of Rides: Step 33: Divide the money left after the admission fee by the cost per ride to find out how many rides each girl can go on.$16.00\$16.00 ÷ $1.00\$1.00 per ride = 1616 rides.
