Answer:
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
Step-by-step explanation:
Given that:
Cost of cell phone at Verizon = $300
Monthly fee = $40
Let,
x be the number of months
V(x) = 40x + 300
Cost of cell phone at T-mobile = $200
Monthly fee = $60
T(x) = 60x + 200
For equal amount of money,
V(x) = T(x)
40x+300=60x+200
300-200=60x-40x
100=20x
20x=100
Dividing both sides by 20
Hence,
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
