question 21:
revenue function: 6.00x -.002x
revenue - cost = profit: 6.00x - .002x^2 - .007x^2 - .51x - 260 5.49x - .009x^2 - 260
differentiates to : 5.49 - .018x -.018x + 5.49
when submitting, i forgot to type the -, so i submitted 30.30. it was the only question i got wrong, so i finished with a 96.88%, so i did not feel like redoing it.
