Answer:
1. a. Allocated prices
First add the market values = 444,150 + 255,150 + 56,700 + 189,000 = $945,0
00
Building allocated price                                     Land allocated price
= 444,150/ 945,000 * 830,000                        = 255,150/945,000 * 830,000
= $390,100                                                           = $224,100
Land improvement allocated price                  Four vehicles allocate price
= 56,700/945,000 * 830,000                          = 189,000/945,000 * 830,000
 = $49,800                                                        = $166,000
b. Journal entry
Date                 Account Details                             Debit                   Credit
Jan. 1, 2017      Building                                       $390,100
                         Land                                            $224,100
                         Land improvement                     $49,800
                         Vehicles                                      $166,000
                         Cash                                                                         $830,000
2. Depreciation on building using straight-line method. 
= (390,100 - 28,000) / 15
= $24,140
3. Depreciation on land improvements using double declining method. 
First do straight line: 
= 49,800/ 5 years
= $9,960
Straight line rate of depreciation = 9,960/49,800 = 20%
Double declining will be twice that rate = 40%
Depreciation = 40% * 49,800 
= $19,920
