Problem 16-4 Change in tax rate; record taxes for four years [LO16-1, 16-5]

Zekany Corporation would have had identical income before taxes on both its income tax returns and income statements for the years 2018 through 2021 except for differences in depreciation on an operational asset. The asset cost $130,000 and is depreciated for income tax purposes in the following amounts:

  
The operational asset has a four-year life and no residual value. The straight-line method is used for financial reporting purposes.
  
Income amounts before depreciation expense and income taxes for each of the four years were as follows.
   

  
Assume the average and marginal income tax rate for 2018 and 2019 was 30%; however, during 2019 tax legislation was passed to raise the tax rate to 40% beginning in 2020. The 40% rate remained in effect through the years 2020 and 2021. Both the accounting and income tax periods end December 31.
   
Required:
Prepare the journal entries to record income taxes for the years 2018 through 2021. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

Target Costing

Laser Cast, Inc., manufactures color laser printers. Model J20 presently sells for $525 and has a total product cost of $420, as follows:

It is estimated that the competitive selling price for color laser printers of this type will drop to $500 next year. Laser Cast has established a target cost to maintain its historical markup percentage on product cost. Engineers have provided the following cost reduction ideas:

1. Purchase a plastic printer cover with snap-on assembly, rather than with screws. This will reduce the amount of direct labor by 9 minutes per unit.
2. Add an inspection step that will add six minutes per unit of direct labor but reduce the materials cost by $11 per unit.
3. Decrease the cycle time of the injection molding machine from four minutes to three minutes per part. Thirty percent of the direct labor and 42% of the factory overhead are related to running injection molding machines.

The direct labor rate is $34 per hour.

a. Determine the target cost for Model J20 assuming that the historical markup on product cost and selling price is maintained. Round your final answer to two decimal places.
$

b. Determine the required cost reduction. Enter as a positive number. Round your final answer to two decimal places.
$

c. Evaluate the three engineering improvements together to determine if the required cost reduction (drift) can be achieved. Enter all amounts as positive numbers. Do not round interim calculations but round your final answers to two decimal places.

Identify whether each of the following statements best illustrates the concept of consumer surplus, producer surplus, or neither.

Choices for each

-(a) Consumer Surplus

-(b) Producer Surplus

-(c) Neither

(1) Even though I was willing to pay up to $43 for a used laptop and even though the seller was willing to go as low as $32 in order to sell it, we couldn't reach a deal because the government imposed a price floor of $49 on the sale of laptops.

(2) I sold a jersey sweater for $34, even though I was willing to go as low as $25 in order to sell it.

(3) Even though I was willing to pay up to $49 for a used textbook, I bought a used textbook for only $43.

(unicellular vs metazoan), use no more than a few short sentences to speculate why one organism might encode the protein (or a similar family member to that identified in question 1) and another may not.

Your reasoning should include reference to the type of protein and how it works in general terms.

3. Identify the topological similarities and differences among the trees. I.e., what relationships are shared across the different phylogenies, and what relationships are different

4. Why do you think all methods did not result in the same tree topology (your answer can be general and does not need to include technical details).

5. Compare your phylogenies to the published phylogeny in Perelman et al. (2011), focusing just on the “Hominidae” clade. Do any of your topologies match their topology? If not, why do you think that might be? Hint: compare the number of species in your phylogeny compared to theirs & compare the number of genes analyzed in their study compared to yours.

Locate a recent article (published within the last year) that includes values for the key economic factors. You can use the Hunt Library, newspapers, new stations, or other credible sources to locate an article. Analyze your selected country's economic well-being. Include the following in your discussion.

• Discuss how nominal and real GDP for your selected country are affected if there is a decrease in taxes and an increase in interest rates.
• Identify and discuss at least six economic indicators for your selected country.
• State the relationship between GDP, net domestic product (NDP), national income (NI), personal income (PI), and disposable income (DI).

Write Matlab code and run them for the following:

a) Motion of a point in a circle

b) Motion of a line in a circle

c) Motion of slider crank mechanism

Mrs. Thomson is a 78 year-old woman whose doctor recently recommended that she have a DXA

scan in order to determine her bone mineral density. The scan results indicate low bone mineral

density. Mrs. Thompson refuses to take pills or supplements and is, therefore, referred to a

dietitian for nutritional counseling.

a.

With Mrs. Thompson’s diagnosis of osteopenia, intake of which micronutrients will be most

critical components in her nutrition plan?

b.

What physiological role do these micronutrients play that makes them so important for her

nutrition plan?

c.

What foods will be included in her diet plan as good sources of these micronutrients?

d.

What other lifestyle changes can Mrs. Thompson make to try to slow the advancement of

her osteopenia?
