Answer:

A.  

0.833

Explanation:

m = 3

Arrival rate, ra = 45 per hour

Service rate, re = 18 per hour per lane

Utilization factor = ra/(m.re)

                            = 45/(3*18)

                            = 0.833

Therefore, The utilization factor of the system is 0.833

Answer:

SafeRide, Inc.

a. The financial implications of accepting the order are that total production cost will increase by $315,000 with a corresponding increase in sales revenue of $540,000, and an increase in net income by $225,000.

b. Under full capacity, the total production cost will increase by $1,485,000 for adding additional facilities while the sales revenue would increase by $540,000, resulting to a loss of $945,000.

c. Under full-capacity circumstances, there is a financing disadvantage of accepting the order because the order will entail additional capacity and facilities, resulting to a loss of $945,000.

Explanation:

Annual production capacity = 300,000 units

Current production capacity = 180,000 units

Special order from a German manufacturer = 60,000 units

Special order price per unit = $9.00

Budgeted Costs For      180,000 Units  240,000 Units  Difference 60,000

Manufacturing costs

Direct materials                 $450,000           $600,000       $150,000

Direct labor                           315,000             420,000          105,000

Factory overhead              1,215,000           1,260,000           45,000

Total                                  1,980,000          2,280,000       $300,000

Selling and administrative 765,000              780,000            15,000

Total                              $2,745,000        $3,060,000        $315,000

Costs per unit

Manufacturing                       $11.00                  $9.50

Selling and administrative       4.25                     3.25

Total                                     $15.25                  $12.75

Selling price to North American manufacturers = $20 per unit

Financial implications of accepting the order:

Manufacturing costs

Direct materials                  $150,000

Direct labor                           105,000

Factory overhead                  45,000

Total                                  $300,000

Selling and administrative    15,000

Total                                  $315,000

Total cost per unit = $5.25 ($315,000/60,000)

Total manufacturing cost per unit = $5 ($300,000/60,000)

Increase in net income from accepting the order = $225,000 ($9.00 - $5.25) * 60,000

Manufacturing costs

Direct materials                  $150,000 (variable)

Direct labor                           105,000 (variable)

Factory overhead              1,215,000

Total                                $1,470,000

Selling and administrative    15,000 (assumed to be variable)

Total                               $1,485,000

Unit cost per additional unit = $24.75

Stock R has a beta of 1.8, Stock S has a beta of 0.75, the expected rate of return on an average stock is 9%, and the risk-free
PIT_PIT [208]

Answer:

Stock R more beta than Stock S = 4.2%

Explanation:

given data

Stock R beta = 1.8

Stock S beta = 0.75

expected rate of return = 9% = 0.09

risk-free rate = 5% = 0.05

solution

we get here Required Return

Required Return (Re) = risk-free rate + ( expected rate of return - risk-free rate ) beta  ...........1

Required Return (Re) = 0.05 + ( 0.09 - 0.05 ) B

Required Return (Re) =

so here

Stock R = 0.05 + ( 0.09 - 0.05 ) 1.8

Stock R = 0.122  = 12.2 %

and

Stock S = 0.05 + ( 0.09 - 0.05 ) 0.75

Stock S =  0.08 = 8%

so here more risky stock is R and here less risky stock is S

Stock R is more beta than the Stock S.

Stock R more beta Stock S =  12.2 % - 8%

Stock R more beta Stock S = 4.2%

Hong invested his savings in two investment funds. The 5000 that he invested in Fund A returned a 3% profit. The amount that he
Snowcat [4.5K]

Answer:

amount invest in B is 2000

Explanation:

given data

invested in Fund A = 5000

return profit A = 3%

return profit B = 10%

both together returned profit =  5%

solution

we consider here amount invest in B = x

so profit from fund B is

profit from fund B =  10% ×  x = 0.1 x

and

profit from fund A = 5000 × 3% = 150

so total profit = 0.1x + 150

and total profit = 5%

so we can say

5%  = \frac{0.1x+150}{5000+x}

solve it we get

x = 2000

so amount invest in B is 2000
