a cab charges the following fare for ea. trip...first 1/4 mi $2.95 for every additional 1/4 mi or part $0.65
(a)what is the fare for a distance of 1 5/8 mi? my answer...I got $8.85
(b) what is the fare for a didtance of 10 3/4 mi? My answer...$30.25
(c)what is the possible distance a customer can travel with $67.20? express the answer to 1 decimal place. i don't know how to do this.

(a) is 2.95 (first 1/4 mile) + 1.5 miles x2.60 ($/mile) = $6.85
(Same charge as as 1 3/4 miles)
(b) is correct
(c) After the first quarter mile, you have $64.25 left to travel at a rate of $2.60 per mile. That will take you an additional 24.5 miles, for a total of 24.75 miles. Total charge: $66.65 The next jump in the meter would take you to $67.30, so you have to stop at 24.75 miles.
