Answer:

difference of cost between two company = 12 - 0.12 x

Step-by-step explanation:

For company ABC

start up fee = $12

cost of one minute call = $0.08

if x minute call are done then cost of x call = 0.08*x = 0.08x

total cost incurred in company ABC= startup fee+ cost of x minute call = 12+0.08X

___________________________________________________

For company WYZ

start up fee = 0

cost of one minute call = $0.20

if x minute call are done then cost of x call = 0.20*x = 0.20x

total cost incurred in company WYZ plan = startup fee+ cost of x minute call = 0+0.20x = 0.20x

______________________________________________

difference of cost between two company = 12+0.08x - 0.20x

difference of cost between two company = 12 - 0.12x (Answer)
