Answer:
Please find the detailed answer as follows:
Explanation:
A. Step 1. The differential equation is
dB / dt = 0.015B - 5000
Step 2.
now we must integrate it to find it ias a function of time
dB /0.015B - 500 = dt
Step 3. integrate
=> ln ( 0.015 B - 5000) = 0.015t + 0.015c
=> 0.015B - 5000 = e^0.015t .e^0.015c
here .e^0.015c is constant let it be Bo
b. =>B = 1/0.015 [ Bo e^0.015t + 5000 ]
at t = 0 , B = 5000
=> 5000 x 0.015 = Bo => B o = 75
c
. B = 1/0.015 [ 75 e^0.015t + 5000 ]
put t = 10
=> B = $ 339142.50
This statement is true.
In Causal forecasting, one tries to base the model on the causes of a particular behavior. These causes are the independent variables.
Forecasting is a method of making informed predictions by using historical data as the primary input for determining future trends. Businesses use forecasts for a variety of purposes. B. To forecast future costs and determine how to allocate budgets.
Causal forecasting is a strategy that predicts or attempts to forecast future events in a market based on a number of variables that are likely to influence future movements within the market.
Based on variables that influence data availability and states of interest, the branches of random methods are segmentation, index methods, and regression analysis. Regression analysis is the most common computable method of random prediction.

Solution :
A firm hires labor till a point where the cost of hiring is equal to the value of the additional revenue it produces.
We know ,
the wage rate = cos of hiring an additional worker
the value of the additional revenue that the firm produces = price x (MPI) marginal product of the labor.
Therefore, the firm will hire when :
Wage = value of the additional revenue it generates
Thus, wage = price x (MPI) marginal product of the labor ...........(i)
Therefore, given :
wage of a worker = $ 45
Price = $ 12
So, 45 = 12 x MPI
MPI = 3.8
So the marginal product of employing three days of labor = 25-18/4-3 = 7
Marginal product of employing four days of labor = 30-25/4-3 = 5
So the 4th day produces less revenue than the cost that it generates.
So, the firm should hire 3 workers.
Answer:
Cullumber Company
The ending inventory is:
= $4,888.
Explanation:
a) Data and Calculations:
Item Units Unit Cost Net Realizable Value Value of Ending
Cameras: Inventory (LCNRV)
Minolta 3 $172 $152 $456 ($152 * 3)
Canon 9 140 170 1,260 ($140 * 9)
Light meters:
Vivitar 13 130 100 1,300 ($100 * 13)
Kodak 16 117 128 1,872 ($117 * 16)
Total value of Ending Inventory based on LCNRV = $4,888
b) The Lower of cost- or net realizable value method of valuing ending inventory determines the value by choosing the lower value between the cost price of the inventory and the net realizable value. The purpose that is served by using the LCNRV method is that it reflects the decrease of inventory value when it goes below its original cost while at the same time it does not recognize the increased market value when the cost is lower.
