Answer:
A.50%.
Explanation:
The price elasticity of demand formula is:
PED = Change in quantity demanded / change in price
plugging the amounts into the formula we obtain:
2 = X / 25%
Now, simply solve for X:
2 x 25% = X
50% = X
Thus, the total quantity demanded would increase by 50%
Answer: To increase sale by 10%, the seller must lower the price of the good by 12.5%.
Explanation: Price elasticity of demand measures the responsiveness of quantity demanded to a change in the price. Since, demand and price for a normal good are negatively related to each other, price elasticity is also negative. It can be calculated using,

Therefore, to increase sale by 10%, the seller must lower the price of the good by 12.5%.
Answer:
The benefit cost ratio is 1.564
Explanation:
The benefit-cost ratio is the ratio of the present value of benefits to the present value of costs. It is thus calculated as follows.
Benefit-cost ratio = Present value of benefits / Present value of costs
Present value of costs = $20,000 + $2,500 (P/A, 10%, 10 years)
= $20,000 + $15,361
= $35,361
Present value of benefits = $9,000 (P/A, 10%, 10 years)
= $9,000 x 6.145
= $55,305
Benefit-cost ratio = $55,305 / $35,361
= 1.564
Answer:
the price per share in the case when A offers B is $200
Explanation:
The computation of the price per share is as follows:
The fair value is
= ($60 + $120) × 50%
= $90
The 50% represent the percentage of equally
Now the price per share is
= $90 + $90 + $20
= $90 + $110
= $200
Hence, the price per share in the case when A offers B is $200
The same is to be considered
