Question 1190157: the international links long distance phone company charges no monthly fee but charges 18 cents per minute for long-distance calls. The World Connections long distance company charges 50 dollars per month plus 10 cents per minute for long distance calls. Compare the World Connections long-distance plan to that of International Links. Under what circumstances is it cheaper to use International Links? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! x=number of minutes
Intl: $0.18x are charges
World: $50+$0.10x for charges
International is cheapest at low levels of use.
50+0.10x=0.18x
50=0.08x
x=625 minutes.
So anything under 625 minutes it is cheaper to use International Links
At 625 minutes, both bills are $112.50

Look at 100 minutes. For IL, it is $18.
For WC it is $50+$10=$60.
