(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.

  • math -

    (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.
