Question

Select the correct answer from each drop-down menu. Paul is comparing the cost of cell phone services. At CellCoA, the phone he wants costs $305 and the unlimited calling plan costs $45 per month. At CellCoB, Paul can purchase the same phone for $350 and get an unlimited calling plan for $30 per month. In how many months will both plans cost the same? These equations, which are graphed below, represent the situation. y = 45x + 305 y = 30x + 350 Here, x represents the number of months and y represents the amount paid.

Answer 1

Answer:

number of months = 3    and   amount paid = 440

Step-by-step explanation:

y=45x+305     1st equation

y=30x+350      2nd equation

Subtract 2nd from 1st

y-y=(45x+305)-(30x+350)

0=45x-30x+305-350

0=15x-45

-15x=-45

x=3

Substitute x in 2nd

y=30(3)+350

y=90+350

y=440
