Question 104761: The profit on a watch is given by P = x^2 – 13x – 80, where x is the number of
watches sold per day. How many watches were sold on a day when there was a
$50 loss? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! For a $50 loss, then the profit was -50.
Find x such that P(x)=-50.
Two solutions
x=15 and x=-2.
Selling (-2) watches doesn't make sense, so your only answer is 15 watches sold.
