While taking a hike in the forest, you find some fossils in layers of sedimentary rocks whose age you later find out is said to

cover a span of 100–400 million years. You decide to send the fossils out for analysis to a company that dates rocks by radioactive decay, and, some weeks later, receive a report informing you that a volcanic ash bed associated with one of the fossils has a 1:1 ratio of 235U: 207Pb. Do these data support or refute the assumed age of the rocks in which the fossil was found? (Note: The half-life of 235U is about 700 million years, and its decay product is 207Pb.) Yes, because the ratio of 235U to 207Pb represents one half-life, and that would be approximately 350 million years old. No, because the ratio of 235U to 207Pb represents one half-life, and that would be about 700 million years old. No, because the rock layers are less than 704 million years old. Yes, because the rock layers are less than 704 million years old.

Answer: Yes, because the rock layers are less than 704 million years old.

Explanation: before sending out the fossil sample for examination it was estimated that to be between 100-400 million years old, the data gotten from the results after proper examination supports earlier findings on the age of the rock. Because the fossil dates back to over 350 million years

During December, Far West Services makes a $4,200 credit sale. The state sales tax rate is 6% and the local sales tax rate is 2.
Lina20 [59]

Answer

Debit Accounts receivable   $4,200

Credit Revenue account       $3,870.97

Credit State Sales tax payable        $232.26

Credit local Sales tax payable         $96.77

Explanation:

When revenue is earned but cash is yet to be received and sales tax are to be accounted for at 8.5%, the entries required are;

Debit Accounts receivable   108.5%

Credit Revenue account       100%

Credit Sales tax payable         8.5%

Given that the sales tax amount is in addition to the credit sale amount, let the sales revenue be R

6% * R + 2.5% * R + R = $4,200

1.085R = $4200

R = $3870.97

States tax = 6% * $3870.97

=$232.26

Local tax = 2.5% * $3870.97

= $96.77

Answer:

                                                                                                   Automated

Sales (19,500 units at $30 per unit)            $585,000            $585,000

Variable expenses                                        409,500               351,000

Contribution margin                                       175,500              234,000

Fixed expenses                                              180,000              252,000

Net operating loss                                          $(4,500)           $( 18,000)

New Cm ratio=  Contribution Margin/ Sales Revenue

                      = $ 234,000 $ 585,000 = 0.4

Break-even point in  dollars=  Fixed Costs/ 1- (variable Cost/ Sales)

                                            =  252,000/ 1- (351,000/ 585,000)

                                             = 252,000/ 1-0.6

                                               = 252,000/0.4= $ 630,000

The resulting $ 630,000 is the break even point at which neither a loss nor a profit is incurred.This can be checked as follows.

Sales                                                                         $ 630,000

Variable Costs  ( 60 % $ 630,000)                          $ 378,000

Contribution Margin                                                   $ 252,000

Less Fixed Expense                                                   <u>$ 252,000</u>

Profit                                                                           <u>       0            </u>

Break even point in units =  Fixed Costs/ Contribution Margin in units

                                         = $ 252,000/ (30-18)

                                          =$ 252,000/ $ 12= 21,000 units

he Talley Corporation had a taxable income of $345,000 from operations after all operating costs but before (1) interest charges
Setler79 [48]

Answer:

(a) The firm's Income tax liability is $59,771.25.

(b) The firm's after-tax income is $233,478.75.

Explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows

The Talley Corporation had a taxable income of $345,000 from operations after all operating costs but before (1) interest charges of $69,000, (2) dividends received of $17,250, (3) dividends paid of $20,700, and (4) income taxes. Its federal tax rate was 21% (ignore any possible state corporate taxes). Recall 50% of dividends received are tax exempt. What are the firm's income tax liability and its after-tax income?

The explanation to the anwer is now given as follows:

Adjusted taxable income = Income after operation - Interest charges + Taxable dividend received ................. (1)

Where;

Income after operation = $345,0000

Interest charges = $69,000

Taxable dividend received = 50% * $17,250 = $8,625

Substituting the values into equation (1), we have:

Adjusted taxable income = $345,000 - $69,000 + $8,625 = $284,625

(a) Income tax liability = Adjusted taxable income *  Tax rate = $284,625 * 21% = $59,771.25

(b) After-tax income = (Adjusted taxable income - Income tax liability) + (50% of dividend received) = ($284,625 - $59,771.25) +  (50% * $17,250) = $224,853.75 + $8,625 = $233,478.75

Z = 2.326

σ = Standard deviation = 8

LT = Lead time = 2.50

Safety stock = = Z × σ × ✓LT

= 2.326 × 8 × ✓2.50
