Answer:
$880
Step-by-step explanation:
If r is the rent charged, then the number of $40 increments of increase will be ...
(r -800)/40
and the number of occupied apartments will be ...
120 -5(r -800)/40
The gross income (g) will be the number of apartments times the rent charged, or ...
g = r×(120 -5(r -800)/40) = (1/8)r(1760 -r)
The equation describes a parabola with zeros at r=0 and r=1760. The vertex will be on the line of symmetry, halfway between those zeros. The maximum gross income will be had when the rent is 1760/2 = 880.
$880 should be charged for rent to maximize gross income.
Step-by-step explanation:
We need to find the value of x for all problems if Y is between X and Z.
For all cases, XZ = XY+YZ
4. XY = 5x, YZ=x, and XZ=25
Putting all values
25 = 5x + x
25 = 6x
5. XY = 12, YZ=2x, and XZ = 28
28 = 12 + 2x
x = 8
6. XY = 4x. YZ=3x, and XZ = 42
XZ = XY+YZ
42 = 4x + 3x
42 = 7x
x = 6
7. XY=2x + 1. YZ = 6x, and XZ=81
XZ = XY+YZ
81 = 2x + 1 + 6x
80 = 8x
x = 10
Answer:
0.5
Step-by-step explanation:
If there are twenty white marbles in a bag of 40, then the chances of drawing a white marble is 20/40, or 0.5: one chance in two of drawing white.
