The price h of a recently bought house plus 10% property tax

The 10% property tax is written as 10/100 = 0.1
Since this percentage is based on the price of the house "h", therefore 10% property tax is written as 0.1h

Therefore, the expression needed would be adding the price of the house "h" to the 10% property tax as follows:
expression is : h + 0.1h
