Trevor went to an amusement park where ride tickets cost $2.50 each. He plans to spend $15.00 on refreshments while at the park. He has a total of $65.00. Write an equation to find the number of ride tickets he can buy.

15 + 2.5t = 65

To write an equation to find the number of ride tickets Trevor can buy, let's use the following variables:

x: the number of ride tickets Trevor can buy
2.50x: the cost of ride tickets

Since Trevor has a total of $65.00 and plans to spend $15.00 on refreshments, the total amount he can spend on ride tickets is $65.00 - $15.00 = $50.00.

Therefore, the equation to find the number of ride tickets Trevor can buy is:

2.50x = 50.00
