Answer:
y = 0.75x+20
Step-by-step explanation:
Given that there is an admission ticket fixed and extra cost of 0.75 per ticket for the rides.
This means even if there is no ride used, enterer has to pay a fixed amount for admission.
Let us find out this admission cost from the given information
If y is the total cost and x no of rides
a) x is the no of rides and y the total cost
b) y = 0.75x+20 is the linear equation to calculate the cost for anyone who only pays for festival admission and rides
(c)
Total cost = Admission charges +0.75 * no of ride tickets.
then y = 0.75x+C
where C is the admission fee
Kendall bought 18 tickets i.e. x= 18 and y = 33.50
33.50 = 0.75(18)+C
33.50=13.50+C
C = 33.50-13.50 = 20.00
Hence admission fee = 20
