Answer:
<u>The annual profit if the baker sells 400 pies would be US$ 12,800</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Annual profit in dollars from selling pies using p n( ) = 52n − 0.05n² , where n is the number of pies sold
Annual sales of the baker = 400 pies
2. Let's solve p for 400 pies
p n( ) = 52n − 0.05n²
p (n₄₀₀) = 52 * 400 − 0.05 * 400²
p (n₄₀₀) = 20,800 − 0.05 * 160,000
p (n₄₀₀) = 20,800 − 8,000
p (n₄₀₀) = 12,800
<u>The annual profit if the baker sells 400 pies would be US$ 12,800</u>
