Nearly 45,000 people died from influenza in the US during 2011's "flu season." The total number of deaths in the US that year from all causes was 3,000,000.

Answer:

Explanation:

Given information is ,

Total influenza case count in the US was 9000000.

Total Population of US is 300000000.

Total number of deaths in the US from all causes =D = 3000000

The number of deaths from as specific virus = The number of death by influenza virus = A =45000.

We have to find the proportional mortality ratio for influenza in 2011.

Formula :

Proportional Mortality Ratio = (Number of deaths from Influenza virus) * 100 / ( Total number of deaths in the Population )

That is ,

Proportional Mortality Ratio =  A/D×100

Now plugging the values = ( 45000 ) × 100 / 3000000

=4500000 / 3000000

= 1.5 %

Out of 100 people death from all causes there is 15 people who died from the influenza virus.

Problem 10A specialty coffeehouse sells Colombian coffee at a fairly steady rate of 280 pounds annually. The beans are purchased
SOVA2 [1]

Answer:

The computations are shown below:

Explanation:

a. The computation of the economic order quantity is shown below:

= \sqrt{\frac{2\times \text{Annual demand}\times \text{Ordering cost}}{\text{Carrying cost}}}

= \sqrt{\frac{2\times \text{280}\times \text{\$45}}{\text{\$0.48}}}

= 229 units

The carrying cost is come from

= $2.40 × 20%

b. Time between placement of orders is

= Economic order quantity ÷Annual demand

= 229 ÷ 280

= 0.8179 years

So,

= 0.8179 × 365 days

= 298.53 days

We assume 365 days in a year

c. The average annual cost of ordering cost and carrying cost equals to

= Holding cost + ordering cost

= (Economic order quantity ÷ 2 × Holding cost)  + (Annual demand ÷ Economic order quantity × ordering cost)

= (229 units ÷ 2 × $0.48) + (280 ÷ 229 units × $45)

= $54.96 + $55.02

= $109.98

d)   Now the reorder level is

= Demand × lead time + safety stock

where, Demand equal to

= Expected demand ÷ total number of weeks in a year

= 280 pounds ÷ 52 weeks

= 5.38461

So, the reorder point would be  

=  5.38461 × 3 + $0

= 16.15 pounds

Total assets were $78,000 and total liabilities were $42,000 at the beginning of the year. Net income for the year was $15,500,
Vaselesa [24]

Answer:

$46,500

Explanation:

Accounting equation is stated as :

Assets = Equity + Liabilities

therefore,

Equity = Assets - Liabilities

Equity at Beginning of the Period :

Equity = Assets - Liabilities

           = $78,000 - $42,000

           = $36,000

Equity at end of the Period

Closing Equity Balance = Opening Balance + Net Income - Dividends

                                       = $36,000 + $15,500 - $5,000

                                       = $46,500
