Solve the problem.Vicki's car rental company charges $20 per day plus $0.25 per mile to rent a car. Joshua's rental company charges $26 per day plus $0.20 per mile. The total daily cost, y, in dollars, of renting the car if x miles are driven can be modeled by the linear system: y = 0.25x + 20 Vicki's y = 0.20x + 26 Joshua's Graph the system. What is the x-coordinate of the intersection point of the graphs? Describe what this x-coordinate means in practical terms. 
A. 50; Both companies charge the same amount for 50 miles driven. B. 100; Both companies charge the same amount for 100 miles driven. C. 120; Both companies charge the same amount for 120 miles driven. D. 55; Both companies charge the same amount for 55 miles driven.
Provide an appropriate response.Suppose that Jody drove 80 miles in 2 hours. Dividing 80 by 2 tells us how many miles Jody drove in each hour. The units for this rate are miles per hour (mi/hr). If we divide 2 by 80 what information would this give us? Give an interpretation of the rate 
. What units would be used for this rate?
