thank you , but I have one last problem.

The revenue function for a dog food company is modelled by the function $R= -40d^2+200d$, where d is the price for a can of dog food. The cost function for the production of the dog food is C= 300 - 40d. At what price(s) for a can of dog food will the company break even?

2. can i answer this question the same way i answered the previous question?
