The taxi costs $2.25 for the first mile plus 15cents for each additional tenth of a mile. For a 5.2 mile trip, Eric payed $10 an
Verizon [17]
2.25 for the first mile. That leaves 4.2 miles.

4 * 0.1 = 0.4

0.15 * 4 = $6.00

0.15 * 2 = 0.3

$6.30 + $2.25 = $8.55

$10.00 - $8.55 = $1.45

The driver's tip was $1.45.
