Question

Mackenzie is driving to a concert and needs to pay for parking. There is an

Answer 1

Answer:

$11, 2t +5

Step-by-step explanation:

She has to pay $5 to enter + $2 * number or hours

Cost of parking for 3 hours

$5 + 3*$2 = 5+ 6 = $ 11

Cost of parking for t hours

$5 + t *$2 = 2t +5

Answer 2

Cost of parking with respect to time can be denoted as a function $c(t)$. (t in hours)

When we park the car we automatically pay 5 dollars no matter how long we stay. So the first step to building our cost function is a simple constant,

$c(t)=5$

But we also given that every hour we will pay 2 extra dollars. This means that after 1 hour we will pay the total of $5+1\cdot2=7$ dollars and after 3 hours we will pay a total of $5+3\cdot 2=\boxed{11}$ dollars.

So our function of cost does depend on time, namely

$\boxed{c(t)=5+2t}$.

Hope this helps.
