Part Two:
For any long-distance call T-Mobile charges a base rate of $15 per month plus $0.05 a minute
that you are on the phone, while Verizon charges a base rate of only $10 per month, but charges
$0.10 per minute for long distance calls. Write the equation that represents the total cost for one month of long distance calls for each company, where y is total cost and x is the amount of minutes used:
T-Mobile:
Verizon:
Using an algebraic method, determine how many minutes the two plans will cost the same.
