There is an automatic feeof $11 just to enter the parking lot, and when he leaves the lot, he will have to pay anadditional $3 for every hour he had his car in the lot. How much total money wouldOliver have to pay for parking if he left his car in the lot for 3 hours? How muchwould Oliver have to pay if he left his car in the lot for t hours?

Answer 1

`\begin{gathered} \text{ \$20} \\ p=11+3t \end{gathered}`

Explanation:

The parking payment is given by a fixed payment and a variable payment.

The fixed pay is $11 and the variable pay is $3 per hour.

If it is 3 hours, the payment would be:

`\begin{gathered} p=11+3\cdot3 \\ p=20 \end{gathered}`

That is, the total payment of the parking if it takes 3 hours is $20

Now, for t hours:

`\begin{gathered} p=11+3t \\ \text{where t is the number of hours} \end{gathered}`
