Answer:
$4000000
Step-by-step explanation:
Given data :
200000 shares at $10 par common stock outstanding
market price of stock = $12 per share
increased par value of stock = $10 ( $20)
Black's paid-in capital--excess of par account = $4000000.
The balance in Black's paid-in capital--excess of par account immediately after the reverse stock spit will be $4000000 because the increased par value of stock from $10 to $20 will be reversed back immediately after the reverse stock hence the paid-in capital--excess before stock split = paid-in capital --excess immediately after reverse stock split
Answer:
-18y + 7yz - 4z
Step-by-step explanation:
Listed price = $1.4 million
Down payment = 20% of $1.4 million = 0.2 x 1,400,000 = 280,000
Amount left to pay = $1.4 million - 280,000 = $1,120,000
Present value of an annuity is given by PV = P(1 - (1 + r/t)^-nt) / r
where: PV = $1,120,000
r = 5% = 0.05
t = 12
n = 30 years.
1,120,000 = P(1 - (1 + 0.05/12)^-(12 x 30)) / 0.05
1,120,000 x 0.05 = P(1 - (1 + 1/240)^-360)
56,000 = P(1 - 0.2238)
P = 56,000 / 0.7761 = 72,148.83
Therefore, the monthly payment is $72,148.83
