Solve the problem.The cost of a tourist package depends on the number of sightseeing stops that you have. The ordered pair 
means that 3 stops cost $150, and the ordered pair 
means that 6 stops cost $210.a) Write a linear equation giving the cost, y, in terms of the number of stops x.b) Using the equation found in part a, find how much it costs for 3 stops.c) How many stops would there be if the cost is $310?
A. y = 20x + 90; $150; 11 hours
B. y = 20x + 90; $150; 13 hours
C. y = 20x + 90; $150; 10 hours
D. y = 20x + 90; $150; 12 hours
