Question

winona paid $135 for a lifetime membership to the zoo, so that she could gain admittance to the zoo for $1.00 per visit. write winonas average cost per visit c as a function of the number of visits when she has visited x times. what is her average cost per visit when she has visited the zoo 135 times? graph the function for x > 0. what happens to her average cost per visit if she starts when she is young and visits the zoo every day? find winonas average cost per visit c as a function of the number of visits when she has visited x times. c(x)= (type an expression.)

Explanation:

Step1: Calculate total cost

The total cost is the sum of the membership - fee and the cost per visit. The membership fee is $135$ and the cost per visit is $1$ dollar per visit. If she visits $x$ times, the total cost $T = 135 + 1\times x=135 + x$.

Step2: Calculate average cost per visit

The average cost per visit $C(x)$ is the total cost divided by the number of visits. So $C(x)=\frac{135 + x}{x}=\frac{135}{x}+1$.

Answer:

$C(x)=\frac{135}{x}+1$
