Dupe's present age = 14 years

Olu's present age = 11 years

Explanation:

Let Dupe's age be x. Let Olu's age be y. Since their ages add up to 25 years, x + y = 25
Eight years ago Dupe's age was double that of Olu's age. Solving by simultaneous equations. Four methods are Elimination Method, Graphical Method, Substitution Method, and Matrix Method. Let us try out Elimination method for solving a pair of simultaneous linear equations that reduces one equation to one that has only a single variable. Once this has been done, the solution is the same as that for when one line was vertical or parallel.
Therefore, eight years ago, Dupe's age was 6 and Olu's age was 3 so that x=2y becomes, 6=2*3. Eight years hence, x=6+8=14 and y=3+8=11. That makes, x or Dupe's age as 14 years and y or Olu's age as 11 years.

Answer: b. reduce taxes and cut back on some social programs

Explanation:

When the Economy is not doing well, Social programs are usually targeted as they usually take a lot of money from the Government's coffers.

It is also a generally held view that reducing taxes as a Fiscal policy can help stimulate the Economy by leaving the public with more funds to invest in and spend on the Economy.

The Government of Ruritania is therefore most likely to combine reducing Social programs as well as reducing taxes. This will have the effect of leaving the Government with some money as it loses revenue from taxes whilst also enabling the public to have more money to invest and to spend which will then lead to Economic growth.

Information on Wolfen Company's direct labor costs for the month of January follows: Actual direct labor rate $5.00 Standard dir

xeze [42]

Answer:

Standard Rate = $ 5.65

Explanation:

Wolfen Company

Actual direct labor rate $5.00

Standard direct labor hours allowed 11,000

Actual direct labor hours 10,000

Direct labor rate favorable $6,500

Using formula to find the unknown figure

Direct Labor Rate variance = Actual Hours ( Standard Rate-Actual Rate)

$6,500= 10,000( Standard Rate-5)

$6,500/10,000 = (Standard Rate-5)

0.65+ 5=Standard Rate

Standard Rate=5+0.65= $ 5.65

We can check by putting it in another formula

Direct Labor Rate variance= (actual hours * standard rate)-(actual hours* actual rate)

$6,500=(10,000*Standard Rate)-( 10,000 *5.0)

$6,500= (10,000*5.65)-( 10,000 *5.0)

$6,500= (56,500)-( 50,000 )

$6,500=$6,500 (favorable) when standard price is higher than actual price

xxMikexx [17]

Answer:

The correct answer is b) a Ponzi scheme.

Explanation:

The Ponzi Scheme is a fraudulent investment operation that involves paying investors interest obtained from the money of new investors (and not from the generation of genuine profits). It is a pyramidal system, in which the only way to share benefits requires that participants recommend and capture (refer) to more clients with the objective that new participants produce benefits to primary participants.

This system does not invest in financial or other instruments, it only redistributes money from some investors to others, so the system works only if the number of investors in the pyramid continually grows; once people stop entering the "business", the scammer is prevented from fulfilling his promise and the pyramid collapses

actual quantity= 25,000 pounds

Explanation:

Giving the following information:

Standard quantity= 2 pounds per units

Production= 12,000 units

Direct material quantity variance= $5,000 unfavorable

Standard price= 120,000/(2*12,000)= $5

<u>To calculate the actual quantity used in production, we need to use the following formula:</u>

Direct material quantity variance= (standard quantity - actual quantity)*standard price

-5,000 = (24,000 - actual quantity)*5

-5,000 = 120,000 - 5actual quantity

125,000/5 = actual quantity

25,000 = actual quantity
