Problema Solution
the average cab ride in a certain city is 7.3 miles. The cost is $3 for the first mile and $0.20 for each additional 1/10 of a mile. Write the formula for the cost of the cab ride function C (x), where x represents the number of miles.

C(x) = 3 + (x - 1)(1/10)*0.20
C(x) = 3 + 2(x - 1)
C(x) = 2x + 1
