Solve the problem.In a certain city, the cost of a taxi ride is computed as follows: There is a fixed charge of $2.80 as soon as you get in the taxi, to which a charge of $2.10 per mile is added. Find a linear equation that can be used to determine the cost, C, of an x-mile taxi ride.
A. C = 2.80x + 2.10 B. C = 4.90x C. C = 3.40x D. C = 2.10x + 2.80
