Answer:

D. $2.67

Explanation:

On the high-low method we compare the diference between the highest level and lowest level of activity.

highest 500 dogs 3,600 (fixed + variable cost)

less

lowest 200 dogs 2,800 (fixed + variable cost)

300 dogs 800 variable cost

800/300 = variable cost per dog = 2.6666667 = (2 + 2/3) variable cost of water bill

800 x (2 + 2/3) + fixed cost = 3,600

2133,3333 + fixed cost = 3600

fixed cost = 3,600 - 2,133.33 = 1,466.66667
