Answer:

Equilibrium Price = 40 ; Equilibrium Quantity = 600

Explanation:

Equilibrium is where : Market Quantity Demanded =  Market Quantity Supplied

Market Quantity Demanded = No. of Consumers x Individual Demand Curve

= N x Qi = 100 [10 - 0.1P] = 1000 - 10P  

Market Quantity Supplied = Qs [Given]  

So, Equilibrium is where :

1000 - 10P = 20 P - 200

1000 + 200 = 20P + 10P

1200 = 30P

P = 1200 / 30 = 40 [Equilibrium Price]

Equilibrium Quantity : Putting Equilibrium price value in Quantity demanded & quantity supplied;

Quantity Demanded = 1000 - 10 (40) = 1000 - 400 = 600

Quantity Supplied = 20 (40) - 200 = 800 - 200 = 600

iren2701 [21]

Answer:

The future value of annual savings is $1,370.30

Explanation:

The amount of annual savings =(Shaan's premium +Anita's premium)*10%

Shann's premium is $790

Anita's premium  is $645

Annual savings =($790+$645)*10%

                          =$143.5

The future value formula is given below:

=-fv(rate,nper,pmt,-pv)

rate is 5% annual interest rate

nper is the 8 years that is the duration of investment

pmt is the annual savings of $143.5

pv is the total amount invested now which is zero

=-fv(5%,8,143.5,0)

fv=$ 1,370.30

Complete question:

Huron Company produces a commercial cleaning compound known as Zoom. The direct materials and direct labor standards for one unit of Zoom are given below:

Standard Quantity or Hours Standard Price or Rate Standard  Cost

Direct materials 4.6 pounds $ 2.50 per pound $ 11.50

Direct labor 0.2 hours $ 12.00 per hour $ 2.40

During the most recent month, the following activity was recorded:

a. Eleven thousand two hundred pounds of material were purchased at a cost of $2.90 per pound.

b. The company produced only 1,120 units, using 10,080 pounds of material. (The rest of the material purchased remained in raw materials inventory.)

c. Five hundred and forty eight hours of direct labor time were recorded at a total labor cost of $6,576.

Solution:

Direct Material price Variance

= (Actual Price - Standard price) x Actual Quantity

= ($2.90 - $2.50) x 10,080 = $4032 (F)

Standard Quantity = 1,120 x 4.6 = 5,152 pounds

Direct Material Quantity Variance

= (Actual Quantity - Standard Quantity) x Standard Price

= (10,080 - 5,152  ) x $2.50 = $12,320 (U)
