Answer:

a. SAR is the Sodium adsorption ratio of the water used for irrigation purpose. SAR is ratio of sodium concentration to that of calcium and magnesium concentration.This value is also useful while managing soils that have high concentration of sodium which can occur naturally in some soils.  Although sodium is a macro-nutrient for plants, higher concentration of sodium can cause the displacement of the calcium and magnesium ions in soil which can affect the soil structure by preventing aggregation of clay in the soil resulting in a decrease in the infiltration rates.

b. EC is the electrical conductivity of the soil which depends on the salinity of the soil. High salinity means more solutes in water and this increases the osmotic potential of the soil solution making it difficult for plants to absorb water.

Answer:

The difference between two WACC is 1.2%.

Explanation:

As we know that

WACC = Ke * Ve / (Ve + Vd (1-Tax))    +   Kd * Vd*(1-tax) / (Ve + Vd*(1-Tax))

Using the Book Value Method:

WACC =             14% *$65 / ($65m + $45m (1-40%))

                    + 6% *$45m*(1-.4) / ($65m + $45m (1-40%))

WACC = 10%  + 1.8% = 11.8%

<u>Using the market value method:</u>

Market Value of Common Stock = Common Shares * Market value per share

Market Value of Common Stock = 10 million * $22.5 per share = $225m

WACC =             14% *$225 / ($225m + $50m (1-40%))

                    + 6% *$50m*(1-.4) / ($225m + $50m (1-40%))

WACC = 12.35%  + 0.7% = 13%

The difference between two WACC is 1.2%.

Becky only eats out at Macaroni Grill and eats out three times per month. She receives a raise from $33,200 to $33,500 and decid
iragen [17]

Answer:

55.58

Explanation:

Data provided in the question;

Initial demand per month, Q₁ = 3

Final demand per month, Q₂ = 5

Initial price, P₁ = $33,200

Final price, P₂ = $33,500

Now,

elasticity of demand using midpoint method is calculated as :

= \frac{\textup{percent change in demand}}{\textup{percent change in supply}}

or

= \frac{\frac{Q_2-Q_1}{\frac{Q_1+Q_2}{2}}}{\frac{P_2-P_1}{\frac{P_1+P_2}{2}}}

on substituting the respective values, we get

= \frac{\frac{5-3}{\frac{5+3}{2}}}{\frac{33,500-33,200}{\frac{33,200+33,500}{2}}}

or

= \frac{\frac{2}{4}}{\frac{300}{\frac{66,700}{2}}}

or

= \frac{0.5}{\frac{300}{33,350}}

= 55.58

Anika [276]

Direct labour rate variance = (3875) unfavourable, Direct labour efficiency rate = (800) unfavourable

<u>Explanation:</u>

<u>Computation of Direct Material Price & Quantity Variance </u>

Direct Material Purchase - Price variance  = (SP minus AP) multiply AQ Purchase  ($1.45 minus $1.48) multiply19000  = ($570) Unfavourable

Direc Material Quantity Variance =(SQ-AQ)SP  =

((20 multiply600)-10500) multiply$1.45 =  $2,175 Favourable

Direct Material Price variance - (SP minus AP)AQ Used  = ($1.45minus $1.48) multiply10500 = ($315) Unfavourable

<u>Computation of Direct Labour Rate & Efficiency Variance </u>

Direct Labour Rate variance  = (SR minus AR)multiply AH  

= ($8 minus $9.25) multiply3100  = -3875 Un Favourable

Direct Labour Efficiency Variance  (SH minus AH)multiply SR  

= ((5 multiply 600) minus 3100)multiply8)  = -800 Un Favourable

A project requires an initial fixed asset investment of $148,000, has annual fixed costs of $39,800, a contribution margin of $1
svetlana [45]

Answer:

The firm needs to sale for 5,708 units to break even finnancially.

Explanation:

<u>We convert the fixed asset investment into an annuity:</u>

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

PV 148,000

time 3

rate 0.15

148000 \div \frac{1-(1+0.15)^{-3} }{0.15} = C\\

C  $ 64,820.590

Now, the amount above the annual fixed cost of 39,800 will be considered a gain for tax purposes, we need to increase it by 21% o give the sales before taxes.

before taxes target contribution:

64,820.59 / 1.20 = 54,017.16

We also have a depreciation component which generates a tax shield:

(148,000 / 3) x 21% = (10,360)

<em>Now, we solve for the break even point of the sum of this components:</em>

39,800 + 54,017.16 - 10,360= 83,457.16‬ dollars

Each units generates 14.62 dollars we divide and obtain the sales per year in untis:

83,457.16 / 14.62 = 5.708,42
