Final answer:
The total cost 'y' that Cory spends at the amusement park is calculated using the equation y = 15 + 2x, where 'x' is the number of rides he takes.
Step-by-step explanation:
The question involves creating an equation to model the total cost that Cory would spend at the amusement park, depending on the number of rides he goes on. Since the amusement park charges a fixed entry fee of $15.00 and a per ride fee of $2.00, the equation to represent the total cost y can be written as: y = 15 + 2x
Where y represents the total cost and x represents the number of rides Cory takes. To solve this problem, we use the concept of linear equations which is a fundamental part of algebra.
