Question

A taxi service charges $1.25 every mile you travel. How much would it cost to drive 5 miles? 8 miles? 20 miles?
Record your answers in the table.
Number of miles (m) Cost in dollars (c)
5 $
8 $
20 $

Answer 1

To calculate the cost of traveling a certain number of miles with a taxi service that charges $1.25 per mile, you can use the formula:

\[ \text{Cost (c)} = \text{Number of miles (m)} \times \text{Cost per mile} \]

Given that the cost per mile is $1.25, we can calculate the cost for 5 miles, 8 miles, and 20 miles.

1. For 5 miles:
\[
c = 5 \text{ miles} \times 1.25 \frac{\text{dollars}}{\text{mile}} = 6.25 \text{ dollars}
\]

2. For 8 miles:
\[
c = 8 \text{ miles} \times 1.25 \frac{\text{dollars}}{\text{mile}} = 10 \text{ dollars}
\]

3. For 20 miles:
\[
c = 20 \text{ miles} \times 1.25 \frac{\text{dollars}}{\text{mile}} = 25 \text{ dollars}
\]

Now, we can fill in the table:

| Number of miles (m) | Cost in dollars (c) |
|----------------------|---------------------|
| 5 | $6.25 |
| 8 | $10.00 |
| 20 | $25.00 |
