Question

Samantha uses the following equation to determine how much a taxi ride is going to cost her, where m is the number of miles traveled during the trip.

$7.00 + $2.30m = $20.80

Using the equation, how many miles did she ride?
A.
6
B.
4
C.
8
D.
5

Answer 1

To find out how many miles Samantha rode, we need to solve the equation:

\[
7.00 + 2.30m = 20.80
\]

First, we'll subtract \(7.00\) from both sides of the equation to isolate the term with \(m\):

\[
2.30m = 20.80 - 7.00
\]

Calculating the right-hand side:

\[
20.80 - 7.00 = 13.80
\]

Now, we have:

\[
2.30m = 13.80
\]

Next, we divide both sides by \(2.30\) to solve for \(m\):

\[
m = \frac{13.80}{2.30}
\]

Calculating the division:

\[
m = 6
\]

Therefore, Samantha rode **6 miles**. The answer is:

**A. 6**
