David uses the function P(d) = 20d - 20 to calculate the net profit of his dog walking business. Where P(d) is the net profit in dollars, and d the number of dogs he walks. Interpret the meaning of the equations below using the context of the problem.

P(3) = 40

Answer 1

Answer:

The function represents the profit of dog in walking buisness as a function of number of dogs, where d represents the number of dogs

P(d) = 20d -20 where d is the number of dogs in this case, as P(3) =40

This means that the number of dogs used in this case is 3 and the net profit is given by 40.
