It cost \( \$ 6.50 \) to enter the carnival. Each ride cost \( \$ 2 \). You have \( \$ 20.50 \). Create an equation that can be used to determine r, the number of rides you can go on.

To determine how many rides you can go on, start with the total amount you have, which is \( \$ 20.50 \). Subtract the entry fee of \( \$ 6.50 \) to find out how much money you have left for rides: \( 20.50 - 6.50 = 14.00 \). Each ride costs \( \$ 2 \), so you can represent the total cost of rides as \( 2r \). Therefore, the equation you can use is: \[ 2r = 14.00 \] Or, rearranged: \[ r = \frac{14.00}{2} \] This simplifies to: \[ r = 7 \] So, you can enjoy 7 rides! If you're feeling adventurous at the carnival, remember to budget wisely! You want to take home some cotton candy or maybe even play some games. As you calculate how much each ride costs, keep track of your funds so you don’t miss out on any of the carnival delights afterwards. Balance your thrills and your treats for the ultimate fun day!
