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.

if average demand for invenrory item is 200 units per day lead time is three days and safety stock is 1-- units the reorder poin
Ronch [10]

please do you mean 1 unit for safety stock or 100 units, will solve for both

Answer:when safety stock =1, Reorder point= 601 units

when safety stock =100,  Reorder point= 700 units

Explanation:

Reorder Point (ROP), also called  reorder level, is the point  of inventoryset by a busness  in which it replenishes its stock of items.

given:

Average demand= 200

lead time = 3

when safety stock =1

Reorder point= (Average demand X Delivery lead time ) + Safety stock

                = (200 x 3 ) +1 = 601 units

when safety stock = 100

   Reorder point= (Average demand X Delivery lead time ) + Safety stock

                = (200 x 3 ) +100 = 700 units

Dean's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Deon $4.75 per pound, and type B
sergiy2304 [10]

Answer:

type B 50 pounds

type A 94 pounds

Explanation:

First we construct the equation system:

\left \{ {{A_q + B_q = 144} \atop {4.75A_q + 5.9B_q = 741.5}} \right. \\

Now we clear one and replace:

A_q = 144 - B_q\\4.75A_q + 5.9B_q = 741.5\\4.75(144 - B_q) + 5.9B_q = 741.5

And we can solve for type B:

4.75\times 144 - 4.75B_q + 5.9B_q = 741.5\\1.15B_q = 741.5 - 684\\B_q = 57.5 / 1.15 = 50

And now we can solve for quantity of A as well:

A = 144 - 50 = 94

<u>Finally we can check the answer if it is correct:</u>

50 x 5.9 + 94 X 4.75 =

   295       +      446,5‬   = 741,5‬

The supply of seats for a psychology class at 10 a.m. is the same as the supply of seats for the same class at 2pm LO5 MO1 There
alex41 [277]

Answer:

The demand for 10 a.m. class is higher than the demand for the 2 p.m. class.

Explanation:

The supply of seats for the psychology class at 10 a.m is the same as the class at 2 a.m. But there is a surplus of seats at 2 a.m class and shortage of seats at 2 p.m class.  

Other things being constant this implies that more students are attending the 10 a.m class than the 2 p.m. class. This shows that the demand for the 10 a.m class is comparatively higher than the demand for the 2 p.m. class.  

This causes a surplus of seats at 2 p.m and shortage of seats at 10 a.m.

Which of the following is not generally regarded as a legitimate reason for gov't to intervene in a market?
Bess [88]

Answer:

C. To enforce property rights

Explanation:

Government intervention in market can be non materistically via regulation , materistically via taxes & subsidy.

Although the second materislistic way of tax, subsidy comes under the perview of 'Government Budget' .

Government budget is anual financial statement showing economy's expected revenue & expenditure .

Economic growth & stability by reallocation of resources , reducing income inequalities - reflect 'efficiency' & 'equity' as valid reasons .

Foreign protection is also not invalid depending upon the initial budding stage of a developing economy & its global stand. Eg - India 1950 to 1990 .

However all these are progressive legitimate reason for govt. Intervention .

But , enforcing property rights is a feature of 'socialistic (communistic) economy - which has its own demerits like loss of consumers soveireignity , lack of postive competitive efficiency , govt overburden.
