solution :

sum of dollar =200+220+280+300+310+320+330+

350+390

Now,

average =<u>total </u><u>sum</u><u> </u><u>of</u><u> </u><u>all</u><u> </u><u>dollar </u>

total sum of worker

A city government is considering two types of town-dump sanitary systems. Design A requires an initial outlay of $405 comma 00

SIZIF [17.4K]

Answer:

Desing A is a better deal as the equivalent annual cost is lower than desing B

Anywa, bot desing cost are above the city collections thus, it cannot afford the sanitary systems unless it raises taxes

Explanation:

<em><u>Desing A </u></em>

F0 405,000

operating and maintenance cost 51,000 for 14 years

Present value of the operating and maintenance cost:

$C \times \frac{1-(1+r)^{-time} }{rate} = PV\\$

C = $ 51,000.00

time = 14 years

rate = 0.07

$51000 \times \frac{1-(1+0.07)^{-14} }{0.07} = PV\\$

PV $446,018.8673

net worth: $ 851,081.87

equivalent annual cost:

$PV \div \frac{1-(1+r)^{-time} }{rate} = C\\$

PV 851,082

time 14

rate 0.07

$851081.87 \div \frac{1-(1+0.07)^{-14} }{0.07} = C\\$

C $ 97,316.904

<u><em>Desing B</em></u>

F0 251,000

operating and maintenance cost 89,000 for 14 years

$C \times \frac{1-(1+r)^{-time} }{rate} = PV\\$

C 89,000.00

time 14

rate 0.07

$89000 \times \frac{1-(1+0.07)^{-14} }{0.07} = PV\\$

PV $778,346.6507

net worth: $ 1,029,346.65

equivalent annual cost:

$1029346.65 \div \frac{1-(1+0.07)^{-14} }{0.07} = C\\$

C $ 117,700.580

Suppose that during the past year, the price of a laptop computer rose from $2,750 to $2,880. During the same time period, consu

icang [17]

Answer: Elasticity of demand is 7.06

Explanation:

P1= $2,750

P2=$2,880

Q1=446,000

Q2=321,000

$Elasticity = \frac{Q2 - Q1}{\frac{Q1 + Q2}{2} } * \frac{\frac{P1 + P2}{2} }{P2 - P1}$

$Elasticity = \frac{321,000 - 446,000}{\frac{446,000 + 321,000}{2} } * \frac{\frac{2750 + 2880}{2} }{2880 - 2750}$

$Elasticity = \frac{-125,000}{383,500} * \frac{2815}{130}$

$Elasticity = - 0.3259*21.6598$

Elasticity = -0.76

Thus, elasticity of demand for laptops is 7.06. This means that laptops are highly price elastic as it is greater than 1.

A competitive firm produces output using three fixed factors and one variable factor. The firm's short run production function i

Nesterboy [21]

Answer:

D) 75

Explanation:

Our initial production function is:

q = 305X - 2X²

we calculate the derivative of q:

(q') = 305 - 4X

MP = 305 - 4X

$10 / $2 = 305 - 4X

5 = 305 - 4X

4X = 305 - 5 = 300

x = 300 / 4

x = 75
