Solve the problem.In a certain city, the cost of a taxi ride is computed as follows: There is a fixed charge of $2.30 as soon as you get in the taxi, to which a charge of $1.90 per mile is added. Find a linear equation that can be used to determine the cost, y, of an x-mile taxi ride.
A. y = 1.90 + 2.30x B. y = 2.70x C. y = 4.20x D. y = 2.30 + 1.90x

Write a system of inequalities that describes the possible solutions to the problem.Andy decides to fence off a rectangular piece of his land to use as a vegetable garden. He has 80 feet of fencing so the perimeter of the fenced in area cannot exceed 80 feet. The length of the garden is to be at least 4 feet longer than the width. The width must be at least 6 feet. Write a system of inequalities that describe this situation. Let w represent the width and l represent the length.
A. l + w ? 80 l ? w + 4 w ? 6 B. l + w ? 80 w ? l + 4 l ? 6 C. 2l + 2w ? 80 l ? w + 4 w ? 6 D. 2l + 2w ? 80 w ? l + 4 l ? 6
