Answer:
A) 400
Step-by-step explanation:
To find the number of apartments filled that produces the maximum revenue, we can
use the vertex formula for a quadratic function ac2 -F bc -F c, given by = —
In this case, the revenue function is R(c) —0.5c2 + 400% where a = 0.5 and b = 400.
The vertex formula for the maximum occurs at c
1
400
Therefore, the correct answer is:
A) 400
