Question

The total profit (P) in dollars of selling toy boat for n boats is given by the function

P(n)=9n - 400. If the total profit was $1265.00, how many boats were sold?
141 10,985 96 185

Answer 1

Let's make the equation equal to the total profit.

9n-400=1265; we need to find n. Let's start by adding 400 to both sides. 9n=1665; let's divide each side by 9. N=185

So, there were 185 boats sold.
