Answer:
3
Step-by-step explanation:
Cost of a basic service = $24.95
Cost for each additional channel = $6.94
Let the number of premium channels = x
Therefore, the cost of x additional channels =6.94x
Total Cost = 24.95+6.94x
Since Kelly's monthly bill is $45.80
24.95+6.94x = 45.80
6.94x = 45.80 - 24.95
6.94x =20.85
x=20.85/6.94
x = 3
The Kellys are receiving three premium channels.
