Let the number of rides be represented by the variable n.
The cost of admission is $5.00, which is the fixed cost, regardless of the number of rides taken.
For each ride, the cost is an additional $5.00. If someone takes n rides, the total cost will be the sum of the admission cost and n times the cost per ride:
Cost = Admission cost + (Number of rides x Cost per ride)
or
Cost = $5.00 + ($5.00 x n)
Therefore, the equation that gives the cost in dollars as a function of the number of rides is:
Cost(n) = 5n + 5, where n is the number of rides.
