6 miles Quite simple
subtract the tip first:
20.00 - 2.00 = 18.00
subtract the 1st mile charge and in brackets number of miles:
18.00 - 1.50 = 16.50 (1)
divide the remaining amount by the 0.90 per mile:
16.50 / 0.90 = 18.333(18.333)
supply the number of miles (nearest mile)
19.333 (19) miles
Unfortunately bradley L forgot to add the initial mile!!! bradley_L be close. However, he forgot that the $1.50 is for the first mile. He calculated the number of miles Kulp got for 90 cents respectively. Add 1 to bradley_L's answer and there you progress.
19 and a third miles.
But if Mr Kulp give the driver a $10 tip, Conrad would stop the meter and drive him at least 30 miles! Source(s):
Too oodles years as a hack.
