Answer:

Step-by-step explanation:
Fixed monthly fee = $20
Amount charged per minute for long distance calls = $0.20
denotes total cost such that
minutes are used for long distance calls.
Amount charged for
minutes for long distance calls 
Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is 
There asking for the equation, and the possible answers are
y = 2x + 6
y = −one halfx + 3
y = −one halfx + 6
y = 2x + 3
477/36= 13.25
You divide the two numbers to see that 36 will go into 477, 13.25 times.
