Problema Solution
In a large city, taxicabs charge $2.00 for the first 1/5 mile and $0.44 for each additional 1/5 mile. Frank has only $7.50. What is the maximum distance he can travel.
Answer provided by our tutors
Let 'x' represent the maximum distance he can travel in 1/5 mile increments, then 'x-1' represents the additional 1/5th miles after the initial 1/5.
2(1/5)+0.44(1/5)(x-1)=7.5
x=81.86
So divide 'x' by 5 to express the distance in miles:
81.86/5.
16.372
So Frank can travel approximately 16 miles.
