Solve the problem.
-The linear equation in two variables y = 3x + 80 models the total cost, y, in dollars, for towing a car x miles. The equation indicates that the towing company charges a fixed amount of $80 to send a truck to pick up the car
Plus a cost of $3 for each mile the car is towed. Find a solution of y = 3x + 80 using 13 for x.
A) (13, 83)
B) (13, 39)
C) (13, 119)
D) (13, 109)
