Answer 1

To determine the cost of each additional hour of parking, we first need to break down the cost Jillian incurred.

1. Base Rate for the First Two Hours:

   • The base rate is $3 for the first 2 hours.

2. Total Hours Parked:

   • Jillian spent a total of 6 hours parking.

3. Hours Beyond the First 2:

   • Additional hours = Total hours - Base hours = 6 hours - 2 hours = 4 hours.

4. Total Cost Paid:

   • The total cost Jillian paid is $31.

5. Cost for Additional Hours:

   • The cost for the additional hours can be calculated as follows:
   • Subtract the base rate from the total cost: \[ \text{Cost for additional hours} = \text{Total cost} - \text{Base rate} = 31 - 3 = 28 \]

6. Cost per Additional Hour:

   • Now, to find the cost for each additional hour, we divide the cost for the additional hours by the number of additional hours: \[ \text{Cost per additional hour} = \frac{\text{Cost for additional hours}}{\text{Additional hours}} = \frac{28}{4} = 7 \]

Thus, the cost for each additional hour of parking is $7.00.
