In a large city, taxicabs charge $3.00 for the first 1/5 mile and $0.30 for each additional 1/5 mile. Frank has only $6.50

What is the maximum distance he can travel (not including a tip for the cabbie)?

Frank can travel a maximum distance of ________ miles.

#1**+1 **

3.00 + .30 N ≤ 6.50

Where N is the number of 1/5 mile increments after the first one....subtact 3.00 from both sides

.30 N ≤ 3.50 divide both sides by .30

N ≤ 35/3 ≈ 11 (1/5 ) mile increments after he first one

So.....he can travel a total of [ 1/5 + 11/5] = 12/5 miles = 2.4 miles
