Solve the problem.In a certain city, the cost of a taxi ride is computed as follows: There is a fixed charge of $2.20 as soon as you get in the taxi, to which a charge of $2.15 per mile is added. Find an equation that can be used to determine the cost, C(x), of an x-mile taxi ride.
A. C(x) = 4.35x B. C(x) = 2.15 + 2.20x C. C(x) = 2.85x D. C(x) = 2.20 + 2.15x
