Arianys took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.70 plus $1 per mile. The total fare was $19.70, not including the tip. Write and solve an equation which can be used to determine xx, the number of miles in the taxi ride.

To determine the number of miles \( x \) in Arianys's taxi ride, we can create an equation based on the information given.

The taxi fare is comprised of a pick-up fee plus a charge per mile. The total fare can be represented as:

\[ \text{Total Fare} = \text{Pick-up fee} + (\text{Cost per mile} \times \text{Number of miles}) \]

According to the problem:

  • The pick-up fee is $1.70.
  • The cost per mile is $1.00.
  • The total fare is $19.70.

We can set up the equation as follows:

\[ 19.70 = 1.70 + 1.00x \]

Now, to solve for \( x \):

  1. Subtract the pick-up fee from both sides:

\[ 19.70 - 1.70 = 1.00x \]

\[ 18.00 = 1.00x \]

  1. Divide both sides by 1.00:

\[ x = 18.00 \]

So, the number of miles in the taxi ride is \( \boxed{18} \).
