Answer:
The correct option is A. 16.95 + 0.05m = 22.95 + 0.02m; 200 min
Step-by-step explanation:
Consider the provided information.
One telephone company charges $16.95 per month and $0.05 per minute for local calls.
Let m is represents the number of minutes.
Therefore, the cost of plane can be represent as:
Another company charges $22.95 per month and $0.02 per minute for local calls.
Therefore, the cost of plane can be represent as:
Now equate both the equations:
For 200 minutes the cost of both plans remains the same.
Hence, the correct option is A. 16.95 + 0.05m = 22.95 + 0.02m; 200 min

The equation that models this scenario
Step-by-step explanation:
First we convert 50 cent into dollar,
1 cent = dollar
1 cent = 0.01 dollar
50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day
According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.
i.e. quantity became 38-4x
Revenue = Price × Quantity
The required equation is given by,
