Answer:
$15,000
Explanation:
Closing retained earnings is the accumulated value of an entity`s profit reserve from its earnings from  both current and past accounting periods.Closing retained earnings is calculated by deducting dividend paid from earnings after tax of the current year and adding the balance to opening retained earnings.
= Opening retained earnings + (Earnings after tax   -  Dividend paid)
Based on the information supplied, the closing retained earnings will be:
                                                                                $
Service Revenue                                                10,000
Total Expenses                                                  (6,000)
Operating profit                                                  4,000
Dividend                                                           <u>  (1,000)</u>
Retained Earnings                                              3,000
Retained Earnings b/f                                      <u>   12,000</u>
Closing Retained Earnings                            <u>     15,000</u>
Note: No information in regard of tax, so the operating profit is used as profit after tax.
 
        
             
        
        
        
Principal Amount P = $ 48000 
Rate of interest r = 6% = 0.06 
Time interval t = 7 
Formula for Interest I = P x r x t => I = 48000 x 0.06 x 7 => I = 2880 x 7 
Total Interest for seven years would be $20,160
        
             
        
        
        
Answer: 75,000 units
Explanation:
Come up with an expression to solve this. 
Assume the budgeted production needed is P. 
P needs 2 pounds of raw materials per unit so raw materials needed are 2P. 
Beginning raw materials for February have to be 30% of the needs of February;
= 30% * 2P
= 0.6P
Ending raw materials for February have to be 30% of March needs so;
= 30% * 100,000 * 2 pounds
= 60,000 pounds 
So;
Budgeted raw materials purchase for February = Raw materials needed + Ending raw materials - Beginning raw materials
165,000 = 2P + 60,000 - 0.6P
1.4P = 165,000 - 60,000
P =  (165,000 - 60,000) / 1.4
= 75,000 units
 
        
             
        
        
        
A I think. not sure though
        
             
        
        
        
B. The demand becomes more elastic
