Answer:

q_{10} = 200P - 800

q_{20} = 400P - 1600

Explanation:

let the supply function be : P = MC

P = 4 + Q/20

therefore Q = 20P - 80 ( supply function )

For 10 firms

Q = 10( 20P - 80 ) = 200P - 800

for 20 firms

Q = 20(20P - 80 ) = 400P - 1600

next determine market supply curve under free entry

AC = 4 + Q/40

Hence ; when Q = 0 , AC = 4   and this is for unlimited number of firms

Consider a no-load mutual fund with $390 million in assets and 15 million shares at the start of the year and with $440 million
Lyrx [107]

Answer:

20%

Explanation:

The computation of rate of return on the fund is shown below:-

Net assets value at the beginning = Total assets ÷ Number of shares

= $390 million ÷ 15 million

= $26 million

Net assets value at the end of the year = (Total assets - Expenses) ÷ Number of shares

= ($440 million - ($440 million × 2%)) ÷ 16 million

= ($440 million - $8.8 million) ÷ 16 million

= $26.95 million

Now,

Rate of return = (Net assets value at the end of the year - Net assets value at the end of the year + Income distribution + Capital gain distribution) ÷ Net assets value at the beginning

= ($26.95 million - $26 million + $4 per share + $0.25 per share) ÷ $26 million

= $5.2 million ÷ $26 million

= 20%
