Answer:

The answer is: after 8 games

Explanation:

You can solve this problem in two ways:

                                        Deanna                        Lise

Start with                            $15                            $13

After 1 game                      $14.25                       $12.50

After 2 games                   $13.50                       $12.00

After 3 games                   $12.75                        $11.50

After 4 games                   $12.00                        $11.00

After 5 games                   $11.25                         $10.50

After 6 games                   $10.50                        $10.00

After 7 games                    $9.75                         $9.50

After 8 games                   $9.00                        $9.00

Or you can solve this equation:

= (price of arcade D - price of arcade L) / (Deanna's money - Lise's money)

= ($0.75 - $0.50) / ($15 - $13) = $0.25 / $2 = 8

Three contractors (call them a, b, and
patriot [66]

Answer:  The probabilities of winning a contract are

P(A) = \frac{28}{36}  

P(B) = \frac{7}{36}  

P(C) = \frac{1}{36}


Let the Probability of C winning the contract - P(C) be 'X'

Then,

Probability of B winning the contract - P(B) will be '7X'     and

Probability of A winning the contract - P(A) will be \mathbf{P(A) = 4 * P(B) = 4*7X = 28X}

Since the total of all the probabilities is 1,

\mathbf{P(A) + P(B) + P(C) =1}

\mathbf{28X + 7X + X =1}

\mathbf{36X =1}

\mathbf{X =\frac{1}{36}}

So,

P(A) = \frac{28}{36}

P(B) = \frac{7}{36}

P(C) = \frac{1}{36}

A company has a processing department with 10 stations. Because of the nature and use of three of these stations, each is consid
julsineya [31]

Answer:

CC100  has $31.25 per hour

CC11O has $250 per hour

CC120 has $62.5 per hour

CC190 has $62.5 per hour

Explanation:

The IDC rate for each department would be the department IDC allocated divided by operating hours as shown below:

CC100

IDC rate=$25,000/800=$31.25 per hour

CC110

IDC rate=$50,000/200=$250 per hour

CC120

IDC rate=$75,000/1200=$62.5 per hour

CC190

IDC rate=$100,000/1600=$62.5 per hour

Judging from the IDC rates of the departments,department CCC110 seems to have the highest IDC rate per hour,which implies that each hour is charged with $250 against the CC100 where each operating hours is just $31.25.

The higher the IDC rate in a department the higher the cost of the output of that department since the cost has to be recovered from output.

What is the expected rate of return on a bond that pays a coupon rate of 9% paid semi - annually, has a par value of $1,000, mat
spayn [35]

Answer:

b. 7.28%

Explanation:

This question is asking for the yield to maturity(YTM) of the bond. You can solve this using a financial calculator with the inputs below. Additionally, adjust the coupon payment(PMT) and time to maturity(N) to semiannual basis.

Time to maturity; N = 5*2 = 10

Face value; FV = 1000

Price of bond; PV = -1071

Semiannual coupon payment; PMT = (9%/2) *1000 = 45

then compute semiannual interest rate; CPT I/Y = 3.64%

Next, convert the semiannual rate to annual rate(YTM) = 3.64% *2

YTM = 7.28%
