A trolley charges $3.00 just to get in the car and $1.00 for each mile traveled. How much would it cost to travel 5 miles? 8 miles? 20 miles?

Question

Solve on paper and record your answers in the table.
Number of miles (m) Cost in dollars (c)
5 $
8 $
20 $

Answer 1

To calculate the total cost of the trolley ride, you need to add the initial charge to the cost of the miles traveled.

The formula for the total cost is: \[ c = 3.00 + (1.00 \times m) \] where \( m \) is the number of miles traveled.

Now let's calculate the cost for each distance:

1. For 5 miles: \[ c = 3.00 + (1.00 \times 5) = 3.00 + 5.00 = 8.00 \]

2. For 8 miles: \[ c = 3.00 + (1.00 \times 8) = 3.00 + 8.00 = 11.00 \]

3. For 20 miles: \[ c = 3.00 + (1.00 \times 20) = 3.00 + 20.00 = 23.00 \]

Now we can record the answers in the table:

| Number of miles (m) | Cost in dollars (c) | |----------------------|----------------------| | 5 | $8.00 | | 8 | $11.00 | | 20 | $23.00 |
