Solve the problem.In a certain city, the cost of a taxi ride is computed as follows: There is a fixed charge of $2.05 as soon as you get in the taxi, to which a charge of $1.90 per mile is added. Find an equation that can be used to determine the cost, C, of an x-mile taxi ride.
A. C = 3.95x B. C = 2.45x C. C = 1.90 + 2.05x D. C = 2.05 + 1.90x
