Vital Silence Corp. has just issued a 30-year callable, convertible bond with a coupon rate of 6.4 percent and annual coupon pay
Aleks04 [339]

Answer:

a. $880.74

b. 13 years

Explanation:

a.  Conversion ratio = Current Value of bond / Conversion price  = 1,000 / 93.4 = 10.71

Conversion price of bond = 10.71 × 28.60  = $306.31

Coupon = Par value of bond * Coupon rate  = $1,000 * 6.4% = $64

Present value of straight debt is calculated below:

Present Value = $64 × [1-(1+7.4%)^-30 / 7.4%] + [$1,000 / (1+7.4%)^30]

= $64*11.93 + $117.46

= $763.28 + $117.46

= $880.74 .

Therefore, the minimum value of bond is $880.74

b. Conversion ratio = 10.71

Current stock price = $28.6

Suppose number of year the stock will take to reach above $1,140 is t.

Conversion value = Current stock price * Conversion ratio*(1+10.8%)^t

$1,140 = $28.6 * 10.71 * (1.108)^t

(1.108)^t = 3.7218

t = 12.8145 year.

t = 13 years

mr Goodwill [35]

Answer:

7.74%

Explanation:

In this question, we use the Rate formula which is shown in the spreadsheet.  

The NPER represents the time period.  

Given that,  

Present value = $1,180

Assuming figure - Future value or Face value = $1,100  

PMT = $105

NPER = 5 years

The formula is shown below:  

= Rate(NPER;PMT;-PV;FV;type)  

The present value come in negative  

So, after solving this, the answer would be 7.74%

maks197457 [2]
He had a large container of 25 quarts. Then he used 25 quarts and 35.9% of the oil remained.
100% - 35.9% = 64.1%
25 quarts ------------------------- 64.1%
 x quarts  -------------------------- 100%
------------------------------------------------
25 : x = 64.1 : 100
64.1 x = 2,500
x = 2,500 : 64.1 = 39.00156 ≈ 39 quarts
39 - 25 = 14 quarts
Answer: 14 quarts of olive oil remained in the container.
