Explanation:
Note: There are mistakes the names of the companies in the requirements a anb b. These correctly restated before answering the question by as follows:
a. Prepare the following consolidation entries required to prepare a consolidated balance sheet immediately after the business combination assuming Power acquired its ownership of Scrub for $291,000. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)
1. Record the basic consolidation entry
2. Record the excess value (differential reclassification entry)
b. Prepare the following consolidation entries required to prepare a consolidated balance sheet immediately after the business combination assuming Power acquired its ownership of Scrub for $262,000. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)
1. Record the basic consolidation entry.
2. Record the excess value (differential) reclassification entry.
<u>The answers and explanation are therefore given as follows:</u>
a. Prepare the following consolidation entries required when Consideration is $291,000
1. Record the basic consolidation entry
<u>Accounts                                              Dr ($)              Cr ($)              </u>
Common Stock                                   91,000
Retained Earnings (w.1)                    175,000
Goodwill (w.2)                                    25,000  
      Investment in Scrub Company                           291,000
<u><em>(To record the elimination of investment and stockholder equity.)   </em></u>
2. Record the excess value (differential reclassification entry)
Note that $25,000 is transferred to Goodwill account in part 1 above. 
The $25,000 is transferred to Goodwill because when the consideration is greater than the net asset value which is calculated as the of Common Stock and Retained Earnings, the difference is the Goodwill.
When Net Consideration is more than the net asset value (Stockholder Equity), then the difference is to be transferred to Goodwill.

b. Prepare the following consolidation entries required when Consideration is $262,000
1. Record the basic consolidation entry
<u>Accounts                                              Dr ($)              Cr ($)              </u>
Common Stock                                   91,000

      Capital reserve (w.4)                                                4,000
<u><em>(To record the elimination of investment and stockholder equity.)   </em></u>
2. Record the excess value (differential reclassification entry)
Note that $4,000 is transferred to Capital Reserve in part 1 above. 
The $4,000 is transferred to Capital Rserve because when the consideration is less than the net asset value which is calculated as the of Common Stock and Retained Earnings, the difference is Capital Reserve.
When Net Consideration is less than the net asset value (Stockholder Equity), then the difference is to be transferred to Capital reserve.
