Answer:
After paying the driver $6.20 left.
Step-by-step explanation:
This question is incomplete, here is the complete question :
"The taxi charges $2.10 for the first mile and $0.90 for each additional mile. After riding 13 miles, you decide that the fare is going to be more than the $20 you have with you. So, you tell the driver to stop and let you out. Then you call a friend and ask your friend to come and pick you up. After paying the driver, how much of your $20 is left."
The taxi charges $20 for the first mile and $0.90 for each additional miles.
Then the fare for riding x miles = (2.10 + 0.90x)
If x = 13 miles
then total fare = 2.10 + 0.90 × 13
= 2.10 + 11.70
= 13.8
If I have $20 with me ten after riding 13 miles money left with me
= 20 - 13.80
= $6.20
After paying the driver $6.20 left.
