Answer:
Y=50x + 200
Step-by-step explanation:
For every month, which is represented by X, the overall price, represented by y, goes up by 50 so we must multiply 50 by the number of months on the plan, X. We also have to factor in the one-time cost of the phone plan itself, which is 200 and ALSO does not go up with every month, so we add 200 to the equation of 50x, giving us 50x + 200, all we have to do from here is show what this equation is doing, which is giving us the answer to Y (the overall price of the plan), and we finish with Y=50x + 200
