To determine the annual profit when the pizza shop owner sells 350 pizzas, we will substitute \( n = 350 \) into the profit function \( p(n) = 32n - 0.04n^2 \).
First, substitute \( n = 350 \) into the equation:
\[ p(350) = 32(350) - 0.04(350)^2 \]
Calculate \( 32(350) \):
\[ 32(350) = 11200 \]
Now calculate \( (350)^2 \):
\[ (350)^2 = 122500 \]
Now calculate \( 0.04(350^2) \):
\[ 0.04(122500) = 4900 \]
Now substitute these values back into the profit equation:
\[ p(350) = 11200 - 4900 \]
Now calculate \( 11200 - 4900 \):
\[ p(350) = 6300 \]
Thus, the annual profit when the pizza shop owner sells 350 pizzas is $6300.
