Final answer:
Juan can buy 6 ride tickets.
Step-by-step explanation:
To determine the number of ride tickets, r, Juan can buy if he has $32 before he pays the admission fee, we can set up the equation:
8 + 4r = 32
Where 8 represents the admission fee and 4r represents the cost of the ride tickets. To solve for r, we can subtract 8 from both sides of the equation:
4r = 24
Then, we can divide both sides by 4:
r = 6
Therefore, Juan can buy 6 ride tickets.
