Answer:
y = 20 + 0.15x
where x = each minute of talk time
y = total cost
domain [0, ∞)
range [20, ∞)
Step-by-step explanation:
Your equation is like that because you always pay $20 per month, no matter how many minutes you used. Then you have 0.15 per minute so use x as a variable placeholder for the actual number of minutes.
domain is starting from 0 because you can't have negative minutes.
range is at least 20 because you pay $20 to use it even if you don't use any minutes. So it can't be less than $20.
I’m not sure what e is in your equation. But I think the answer is t=5000 months. Let me know if you need an explanation
