For 20 minutes of local calls per month, the cost of plan will be same.
Step-by-step explanation:
Per month charges of one company = $16.95
Per minute charges = $0.50
Let,
x represent the minutes.
T(x) = 0.50x+16.95
Per month charges of another company = $22.95
Per minute charges = $0.20
C(x) = 0.20x+22.95
When the cost will be same, the functions will be equal.
T(x) = C(x)
Dividing both sides by 0.30
For 20 minutes of local calls per month, the cost of plan will be same.
