Question

The function g(x) = 10.73 + 8.14(x - 1) represents the charge for parking at the airport for x number of days. Which statement best represents the formula for this charge?

Answer 1

Answer:

This function states that the first hour has a fixed cost of 10.75.

Then, every additional hour has an additional cost of $8.14.

Step-by-step explanation:

The given function is

$g(x)=10.75+8.14(x-1)$

The statements that best represent the formula are:

• This function states that the first hour has a fixed cost of 10.75.
• Then, every additional hour has an additional cost of $8.14.

You can deduct that from the formula, because $x$ represents hour, so for $x=1$, we have

$g(0)=10.75+8.14(1-1)=10.75$

Which means 1 hour costs $10.75.

Then, for $x=2$

$g(2)=10.75+8.14(2-1)=10.75+8.14=18.89$

Which means an additional hour cost $8.14 additionally.
