$$C = q^3 - 8.5q^2 + 14q + 60$$, where $q$ is the output level. Please answer the following 3 questions:

(1) Determine the output level at which he maximizes profits if the price of \( q \) is 4 dollars per unit (e.g., \( p = 4 \)). (10%)

The market rate of interest is 20%. Please answer the following 2 questions:
