a. Answer:  D: (∞, ∞)
                    R: (-∞, ∞)
<u>Step-by-step explanation:</u>
Theoretical domain is the domain of the equation (without an understanding of what the x-variable represents).
Theoretical range is the range of the equation given the domain.
c(p) = 25p
There are no restrictions on the p so the theoretical domain is All Real Numbers.
Multiplying 25 by All Real Numbers results in the range being All Real Numbers.
a) D: (∞, ∞)
    R: (-∞, ∞)

b. Answer:  D: (0, 200)
                     R: (0, 5000)
<u>Step-by-step explanation:</u>
Practical domain is the domain of the equation WITH an understanding of what the x-variable represents.
Practical range is the range of the equation given the practical values of the domain.
The problem states that p represents the number of cups.  Since we can't have a negative amount of cups, p ≥ 0.  The problem also states that Bonnie will purchase a maximum of 200 cups. So, 0 ≤ p ≤ 200 
The range is 25p →  (25)0 ≤ (25)p ≤ (25)200 
                              →      0   ≤  25p  ≤  5000
b) D: (0, 200)
    R: (0, 5000)

Answer:
D+B 12
Step-by-step explanation:
 
        
             
        
        
        
Amount of water that the faucet leaks in 1 week = 42 gallons
 That means Amount of water that the faucet in Kali's house leaks in                 7 days = 42 gallons So The amount of water that the faucet in Kali's house leaks in 1 day = (42/7) gallons  = 6 gallons Then The amount of water that the faucet in Kali's house leaks in 3 days = 6 * 3 gallons = 18 gallons
So it can said from the above deduction that the amount of water leaked by the faucet in Kali's house is 18 gallons.
