Answer
9.42 dollars
Work Step by Step
We find the cost for a ten mile ride for each company. For Uber:
$$=7.25+(2.89)(38) \\ = 117.07$$
For the taxi:
$$ = 10.75+ (38)(2.55) \\ = 107.65$$
For the Lyft:
$$ =8.6+ (2.76)(38) \\ = 113.48$$
By getting a taxi, the amount you would save over the Uber is:
$$ 117.07-107.65 \\ = 9.42$$
