Property Tax

A county collects property taxes on the assessment value of property, which is $60$ percent of the property's actual value. If an acre of land is valued at $$10,000,$ its assessment value is $$6,000.$ The property tax is then $$0\mathrm{.}64$ for each $$100$ of the assessment value. The tax for the acre assessed at $$6,000$ will be $$38\mathrm{.}40.$ Create a GUI application that displays the assessment value and property tax when a user enters the actual value of a property.
