Answer:
$18,396
Explanation:
Average sales of the store per day = $1,680
Number of days in a year = 365
Total sales in a year = $1,680 x 365 = $6132,200
Shrinkage rate = 3%
Losses for an entire year = 0.03 x $6132,200 = $18,396
Answer:
The options are given below:
A) competitively exclude other predators.
B) prey on the community's dominant species.
C) allow immigration of other predators.
D) reduce the number of disruptions in the community.
E) prey only on the least abundant species in the community.
the correct option is B
Explanation:
Keystone species refers to a predator which prevents a particular herbivorous species from wiping out the dominant plant species. If the number of prey are low, the keystone predators can be less abundant and still be effective. Keystone species have a disproportionately large effect on its environment relative to its abundance.
Therefore, by preying on a community's dominant species, keystone predators help to maintain the species diversity in the community, because they ensure that the dominant predators do not totally wipe out the various organisms present in the ecosystem.
Answer:
PV Index = 1.158
Explanation:
Present value index is the ratio of discounted cash flows of the project divided by initial outlay required for the project thus first we calculate the Present Values for Investment B
Present value factors @ 12% for year 0, 1, 2, 3, 4 respectively.
1
0.893
0.797
0.712
0.636
Net Present Value = -9000 + (5000 * 0.893) + (4000 * 0.797) + (3000 * 0.712) + (1000 * 0.636)
NPV = $1425
Present value Index = NPV / Initial investment = 1425/9000 = 0.158
This can be interpreted as 1 + 0.158 = 1.158,
1 being the initial investment. You can also choose not to subtract the initial outlay when calculating NPV.
Hope that helps.
