Suppose you are trying to choose between 2 plans for your long distance telephone service. If you choose plan 1, your monthly bill will be computed according the equation:
Plan 1 B=$30+.20T
B is your monthly billing fee in dollars and Tis your monthly volume of long distance calls in minutes. If you choose plan 2, your monthly bill will be computed according to the equation B=$80+.30T
Please use the algebraic approach to find the breakeven level of monthly call volume for these plans. (Solve equations simultaneously) B. Please graph your points
