Question

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 $x$, the number of miles in the taxi ride.
answer
equation: $1.70 + 1x = 19.70$
answer: $x=$

Explanation:

Step1: Isolate the term with x

Subtract 1.70 from both sides of the equation $1.70 + 1x=19.70$.
$1x=19.70 - 1.70$

Step2: Calculate the right - hand side

$1x = 18$
Since $1x=x$, then $x = 18$.

Answer:

$18$
