Answer:

minimum number of server is = 2

so correct option is B) 2

customers = 4

service time = 18 minutes per customer = \frac{18}{60}  hr = 0.3 hr

to find out

minimum number of server    

solution

we get here first min servers that is

min servers = 4 × 0.3  

min servers = 1.2

so here minimum number of server is = 2

servers cant be in fractions ( as only whole number of server is possible)

so correct option is B) 2

Answer:

The present  value of the dividends to be paid out over the next six years if the required rate of return is 15 percent is $6.57

Explanation:

Solution:

Given that

The present value =∑ ⁿ t=1 cf/ (1 +r)t

where cf= cash flow

r =the required rate of return

t = the number of years

Now

The present value will be:

cf₁/(1+r)^1 + cf₂/(1 +)^2 + cf₃/(1+r)3 + cf₄/(1 +r)^4) + cf₅/(1 +r)^5 + cf₆/(1+r)^6

Hence,

cf₁, cf₂ cf₃ = 0 as the firm does not expect to pay dividend in the next three years

Note: Kindly find an attached document of the part of the solution to this given question

Vanessa bought a house for $268,500. She has a 30 year mortgage with a fixed rate of 6.25%. Vanessaâs monthly payments are $1,59
Musya8 [376]

Answer:

Ans. A) $9,314.45

Explanation:

Hi, first we have to bring to present value the monthly payments to be made for 30 years (360 months). In order for this to be useful, we have to convert this annua compounded monthly rate (6.25%) to an effective rate, that is 6.25% / 12 = 0.5208%. Now, when we find this present value, we are going to substract it from the price of the house and that is the value of the down payment. But let´s just go ahead and do it together.

We have to use this formula to bring to present value the $1,595.85 monthly payments, for 30 years (360 months) at a rate of 6.25% (0.5208% monthly).

PresentValue=\frac{A((1+r)^{n}-1) }{r(1+r)^{n} }

It should look like this

PresentValue=\frac{1,595.85((1+ 0.005208 )^{360}-1) }{0.005208(1+0.005208)^{360} }

Present Value=259,185.55

Now, let´s go ahead and find the down payment.

DownPayment=Price-PresentValue

DownPayment=268,500-259,185.55= 9,314.45

So, the answer is a). $9,314.45

Best of luck.
