Answer:
option D "The demand is unitary elastic."
Explanation:
Data provided:
At price, P1 = 3,000 units
Demand, D1 = $ 50
also,
at price P2 = $ 60
Demand, D2 = 2,500 units
Now,
the percentage change in price = 
or
the percentage change in price = 20%
and,
The percentage change in the quantity = 
or
The percentage change in the quantity = -20%
The elasticity in demand (Ed) is given as:
Ed = (Percentage change in quantity) / (Percentage change in price)
on substituting the values, we get
Ed = (-20%) / 20%
or
Ed = - 1
Here the negative sign depicts the inverse relation between the price and the demand.
hence, the correct answer is option D "The demand is unitary elastic."
No it does not get a period after the abbreviation.
Answer:
44,000*n dollar
Explanation:
If a machine produce 200 per day at the rate of 11 dollars each and she has 20 days. This implies that each machine will produce 44,000 dollar
Therefore for n machine, she will have money m of 44,000*n dollar
Answer:
The interest revenue is $ 300+$315.62+$887.67+$4500= $ 6003.29
Explanation:
Note 1 : Interest Revenue = $ 30,000 * 4% *3/12= $ 300
Note 2 : Interest Revenue= $ 16,000 * 8 % *90/365= $ 315.62
Note 3: Interest Revenue= $ 18,000 * 10% *180/365= $ 887.67
Note 4: Interest Revenue= $ 150,000 * 12% *6/12= $ 4500
