Answer: BP = BD(WD) + BE(WE)
1 = 0.86(1-WE) + 1.39WE
1 = 0.86-0.86WE + 1.39WE
1 = 0.86 + 0.53WE
-0.53WE = -0.14
0.53WE = 0.14
WE = 0.14/0.53
WE = 0.2641509434
WD = 1 - WE
WD = 1 - 0.2641509434
WD = 0.7358490566
The dollar amount of investment in stock D = 0.7358490566 x $215,000
= $158,207.54
Explanation: The beta of the portfolio is 1, which corresponds to the beta of the market. The beta of the portfolio equals beta of each stock multiplied by the percentage of fund invested in each stock(weight). The weight of stock D is equal to 1 - weight of stock E. Therefore, we need to make weight of stock E the subject of the formula by solving the problem mathematically and collecting the like terms. The weight of stock E is 0.2641509434. The weight of stock E will be subtracted from 1 so as to obtain the weight of stock D, which is 0.7358490566. The dollar amount of stock D equal to $215,000 multiplied by 0.7358490566, which is $158,207.54.
to make sure business is conducted safely and fairly
The government creates regulations in order to make sure business is conducted safely and fairly. Without regulation the market would have to auto regolate itself, which is a thing that it does, but the cost of this autoregulations are often too much. The government can help create basic directories to ensure that the trade is safe done.
Answer:
the price elasticity of supply is 0.555
Explanation:
The computation of the price elasticity of supply is given below:
= Percentage change in quantity supplied ÷ percentage change in price
= (25 - 20) ÷ (25 + 20) ÷ 2 ÷ (750 - 500) ÷ (750 + 500) ÷ 2
= 5 ÷45 ÷ 250 ÷ 125
= 0.555
Hence, the price elasticity of supply is 0.555
