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.

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

 

 

cool cool cool
