First, please write a command predicate called
tax that takes five arguments. The
first argument is an initial; the second is a title (i.e.
'Mr' ); the
third is a surname; the fourth is an address. All these are atoms. The
fifth is a number, representing an amount of money in pounds. An example
of its use: the question
tax( 'D', 'Mr', 'Jones', 'Honeysuckle Cottage, Woodtown', 2500 ).should display the message

Unless you pay this within a period of 7 days, your possessions, including any children you may have accrued, will be liable to distraint in order to pay the above-mentioned sum of 2500 pounds.

must be a number. Load this by typing
