Answer:
the opportunity cost of the land purchase is $34,050
Explanation:
The computation of the opportunity cost of the land purchase is shown below;
= Cash outlay × return percentage
= $227,000 × 15%
= $34,050
Hence the opportunity cost of the land purchase is $34,050
We simply multiplied the cash outlay with the return percentage so the same would be calculated
In order to break even, they would need to sell at least 5,000 units
Break even point is calculated by the formula:
Fixed costs÷(selling price -variable costs per unit)
i.e.
100,000 ÷ (60-40) = 5,000
Anything they sell above this number will start to produce profits for the company
Answer:
A. 0.3204 B. $14.669
Explanation:
Mean = 8.9 SD = 4.5
Required probability = P (X >/= 550/50)
P(X>/=11) = 1 - P[(X - mean/SD) < (11 - mean)/SD]
= 1 - P(Z < (11-8.9)/4.5)
P(X>/=11) = 1 - P(Z < 0.4666667)
Using Excel NORMDIST(0.4666667,0,1,1)
P(X>/=11) = 1 - 0.6796 = 0.3204
The probability that she will earn at least $550 = 0.3204
b. P
(
X > x
) = 0.10
1 − P
(
X − mean)/SD ≤ (x − mean)
/SD = 0.10
P
(
Z ≤ z
) = 0.90
Where,
z = (x − mean
)/SD
Excel function for the value of z:
=NORMSINV(0.9)
=1.282
Hence (x - mean)/SD = 1.282
= (x - 8.9)/4.5 = 1.282
x = (1.282*4.5) + 8.9
x = 14.669
He earns $14.669 on the best 10% of such weekends.
