Answer:
$335000 and $1425000
Step-by-step explanation:
The values given are:
-Demolition of old building=$ 20,000 
-Architect's fees=$35,000 
-Legal fees for title investigation and purchase contract=$5,000 
-Construction costs=$1,390,000 
-Salvaged materials resulting from demolition=$10,000
-Cost of factory site= $320000
Therefore,
1) The cost of land is:
 $320000+$5000+$20000-$10000
 = $335000
2) The cost of the new building is:
 $35000+$1390000
 = $1425000
Thus, the cost of the land and new building is $335000 and $1425000 respectively.
