mina [271]

Answer:

variable costs

Explanation:

Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments

If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.  

Hourly wage costs and payments for production inputs are variable costs

gvWegmans Bakery produces cheese cake for sale. The bakery which operates 5 days per week and 52 weeks per year can produce cake
Nana76 [90]

Answer:

(a) the optimal production run quantity (Q) = 633

(b) the total annual inventory cost (AHC AOC)  = $ 3,162.28

(c) the optimal number of production runs per year = 7

(d) The run length (production run time) = 16 days

Explanation:

(a) the optimal production run quantity (Q).

optimal production run quantity = √(2×Annual Demand×Setup Costs) / Holding Costs

                                                      = √(2×4000×$250)/ $5

                                                      = 633

(b) the total annual inventory cost (AHC AOC).

total annual inventory cost = Setup Costs + Holding Costs

                                            = 4,000/633×$250+633/2×$5

                                            = $1,579.78+$1,582.50

                                            = $ 3,162.28

(c) the optimal number of production runs per year.

number of production runs per year = Total Demand / optimal production run quantity

                                                            = 4,000/633

                                                            = 7

(d) The run length (production run time).

production run time = optimal production run quantity / produce

                                 = 633 / 40 cakes

                                 = 16 days

Current ratio includes current assets and current liabilities

While on the other hand, the acid test ratio or quick ratio include quick asset and current liabilities

Quick asset = Total Current assets - inventory - all other current assets  

As inventory takes more time to convert into cash
