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.

Step-by-step explanation:
Given that the aquarium is in the shape of a right rectangular prism in which
Length L = 6 1/4 feet
Width W = 7 1/5 feet
Height H = 4 1/2 feet
