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.

Summary financial information for Paragon Company is as follows. Dec. 31, 2014 Dec. 31, 2013 Current assets $ 203,600 $ 254,000
beks73 [17]

Answer:

Current assets:

Amount = 2014 value - 2013 value

             = $203,600 - $254,000

             = -($50,400) (Negative)

percentage changes = \frac{Amount}{2013\ value}\times100

                                    = \frac{50,400}{254,000}\times100

                                    = (19.84)%

Plant assets:

Amount = 2014 value - 2013 value

             = $1,397,000 - $831,700

             = $565,300

percentage changes = \frac{Amount}{2013\ value}\times100

                                    = \frac{565,300}{831,700}\times100

                                    = 67.96%

Total assets:

Amount = 2014 value - 2013 value

             = $1,600,600 - $1,085,700

             = $514,900

percentage changes = \frac{Amount}{2013\ value}\times100

                                    = \frac{514,900}{1,085,700}\times100

                                    = 47.42%

Amberjack Company is trying to decide on an allocation base to use to assign manufacturing overhead to jobs. The company has alw
svetoff [14.1K]

Answer:

Results are below.

Explanation:

Giving the following information:

Estimated Value Actual Value

Manufacturing overhead cost $732,000 $842,000

Direct labor hours 14,640 hours 16,600 hours

<u>To calculate the predetermined manufacturing overhead rate we need to use the following formula:</u>

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Predetermined manufacturing overhead rate= 732,000 / 14,640

Predetermined manufacturing overhead rate= $50 per direct labor hour

<u>Now, we can allocate overhead:</u>

Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base

Allocated MOH= 50*16,600

Allocated MOH= $830,000

<u>Finally, the over/under allocation:</u>

Under/over applied overhead= real overhead - allocated overhead

Under/over applied overhead= 842,000 - 830,000

Underapplied overhead= $12,000
