1. The price of the hat should be $6 if they want to make maximum profit. The profit would be $15,400

2. The minimum price to make a profit needs to be above $2 since the profit for $2 is $0.

3. P(0) is about −$19,250 which means if they charge $0 for the hats, they will lose money.

4. To make $13,700 they can sell the hats for about $4. 50 or about $7

5. For a profit, the domain is (2, 10) and the range would be (0, 15400]

6. The profit increases when the price is less than $6 6. The profit increases when the price is less than $6. The profit decreases when the price is greater than $6

7. The profit increases the fastest from 2 to 3 because that section of the graph is the steepest

8. The best price is $6 per hat. The profit decreases after $6 and if the hat is sold for more than $10, the owner will lose money.
