Solve
First, place the unknown x on the left.
Then, solve for x.
Answer:
D
Step-by-step explanation: The vertex is where the curve of the parabola occurs. Pay attention to where the curve of the parabola exists, and write down its coordinates. Over here, the curve is on 3 of the x-axis, and the y-value is 0 because the curve is literally on the x-axis. Any point that is on the x-axis will have no y-value. Hence our answer is (3,0).
Let x = # of rent bumps
revenue = # occupants * rent per unit occupied
revenue = (170 - x) * ( 510 + 1.5*x)
in our problem, revenue (the money streaming in)
is the same as the profit, since no cost is given in the problem.
profit = (170 - x) * ( 510 + 1.5*x)
<span>to maximize this we use the derivative</span>
False if 0 is a whole number
