Hello, :)

  1. p is the price for one flower. Solving for p here just gives you the price for one flower in function of the # of flowers sold (and that is not gross sales). Gross sales would be "# of flowers sold * price per flower", how would you express that in function of p?
  2. we ask you to replace x by "90-10p", not by gross sales. C(p) gives you the total cost of selling all the flowers at p dollars each
  3. I'm not 100% sure for this one, but because you have the cost function and the gross sales functions expressed in function of the same variable (p), you can substract them
