To calculate the cost of traveling a certain distance with the trolley, you can multiply the distance in miles by the charge per mile.
-
Cost for 5 miles: \[ 5 \text{ miles} \times 2.00 \text{ dollars/mile} = 10.00 \text{ dollars} \]
-
Cost for 8 miles: \[ 8 \text{ miles} \times 2.00 \text{ dollars/mile} = 16.00 \text{ dollars} \]
-
Cost for 20 miles: \[ 20 \text{ miles} \times 2.00 \text{ dollars/mile} = 40.00 \text{ dollars} \]
So, the costs are:
- Traveling 5 miles costs $10.00.
- Traveling 8 miles costs $16.00.
- Traveling 20 miles costs $40.00.
