(Assume that n is a postive integer) How many units are produced when the profit is \$430?Answer by ewatrrr(10682)   (Show Source): You can put this solution on YOUR website! ``` Hi, P= 3n^2-30n-170 P = \$430 430 = 3n^2 - 30n - 170 OR 3n^2 -30n - 600 = 0 n^2 - 10n - 200 = 0 factoring (n - 20)(n + 10) = 0 ||ony positive solution is appropriate n = 20, number of units produced when the profit is \$430 ```
