Company A charges $25 per month plus $0.22 per minute for cell phone service. Company B charges $35 per month plus $0.12 per minute. How many minutes of usage is needed in one month to make Company B a better deal?

Answer 1

Okay so I'm not sure if I'm interpreting this question properly but this is what i gathered:
We can write an equation for Company A deal... Let P = payment and m = minutes
P for Company A = 25 + 0.22(m)
and we need to calculate how many minutes it will take for us to reach 35 dollars through this deal because afterwards, B becomes a better deal.
So if you go 35 = 25 + 0.22(m) and solve for m, you will get 45.45 minutes. That is how many minutes it will take to be equal to company B. and so >45.45 minutes in company A will make company B a better deal ASSUMING that you are only charged the flat fee in B...
