Solve the problem.In a certain city, the cost of a taxi ride is computed as follows: There is a fixed charge of $2.75 as soon as you get in the taxi, to which a charge of $1.55 per mile is added. Find an equation that can be used to determine the cost, C, of an x-mile taxi ride.
A. C = 1.55 + 2.75x B. C = 2.75 + 1.55x C. C = 2.80x D. C = 4.30x
