Question

The total cost f(x), in dollars, for renting a bike for x hours is shown:

f(x) = 10 + 20x

What does f(10) represent?

Answer 1

f(10) represents the total cost, in dollars, for renting a bike for 10 hours, which is $210.

Step-by-step explanation:

Step 1: Understand the expression:

The expression f(x) = 10 + 20x represents the total cost of renting a bike for x hours. The constant term 10 represents the initial fixed fee, while the variable term 20x represents the hourly rental fee.

Step 2: Substitute the given value of x:

We are given that x = 10. Substituting this value into the expression, we get:

f(10) = 10 + 20(10)

Step 3: Simplify the expression:

Multiplying 20 by 10 and adding the result to 10, we get:

f(10) = 10 + 200 = 210

Interpretation:

Therefore, f(10) = 210 represents the total cost of renting a bike for 10 hours. This means that if you rent a bike for 10 hours, you will be charged a total of $210.

Answer 2

The number of hours because f(10) you would plug 10 in as x
