Answer:

D

Step-by-step explanation:

($20/hr) is the hourly rental rate, and x is the number of hours for which the bike is rented.

In    f(x) = 10 + 20x   letting x = 10 results in the total rental cost of the bike for 10 hours (Answer D)

The value of the function at x =10, represents the number of dollars it costs to rent the bike for 10 hours, the correct option is D.

What is a Function?

A law that relates two variables is called Function.

The function for the total cost of renting a bike is given by

f(x) = 10+20x

f(10) means x = 10

f(x) = 10+20*10=$210

It represents the number of dollars it costs to rent the bike for 10 hours.

Therefore, the correct option is D.
