When identical units of an item are purchased at different costs: <span>an inventory cost flow method must be used under both a perpetual and a periodic inventory system.
A perpetual inventory system will update your inventory on hand after each sale or purchase of inventory is made. A periodic inventory system is updated periodically, meaning, a company will give a time period they would like their sales and purchases to update in and the system will perform that. Both systems are great for a business but it's their option of how they are generated.

Answer:
In the case of age 30, there will be more money at the age of 60
Explanation:
When person start investing at the age of 20 then total year till 60 years age is = 40 years.
Interest rate (r ) = 7 percent or 0.07.
Investment amount (Present value) = $1000
Now the total amount at the age of 60 years is calculated below.

Now calculate the total amount at the age of 60 years when he invest at the age of 30 and earns interest rate 10 percent. Now the number of years is 30.

Is this a question or what is this.
Answer:
C) ABC 5% and DEF 5.7%
Explanation:
Data provided in the question:
Purchasing Cost of Stock ABC purchased = $40 per share
Purchasing Cost of Stock DEF purchased = $35 per share
Time = 6 months
Selling price of share of ABC = $42 per share
Selling price of DEF share = $36
Dividend paid to the DEF = $0.5 each quarter i.e $0.5 twice in 6 months
Thus,
Total dividend paid to DEF = $0.5 × 2
= $1
Now,
For ABC
Total return = Selling price - Purchasing Cost
= $42 - $40
= $2 per share
thus,
Holding period return = [ Total return ÷ Purchasing cost ] × 100%
= [ $2 ÷ $40 ] × 100%
= 5%
For DEF
Total return = Selling price + Dividend received - Purchasing Cost
= $36 + $1 - $35
= $2 per share
thus,
Holding period return = [ Total return ÷ Purchasing cost ] × 100%
= [ $2 ÷ $35 ] × 100%
= 5.7%
Hence,
option C) ABC 5% and DEF 5.7%.
Answer: c. Contribution margin ratio = 1 − Variable cost ratio
Explanation:
The Contribution margin ratio is defined as the difference between the sales price of a good and it's variable costs. It is expressed as a percentage.
The formula is,
Contribution Margin Ratio = Sales - Variable Costs / Sales
Breaking the formula down further we have,
Contribution Margin Ratio = Sales/ Sales - Variable Costs / Sales
Contribution Margin Ratio = 1 - Variable Costs / Sales
Variable Cost/Sales is the Variable Cost Ratio.
So Option C is correct.
