Write structured English to solve the True Disk company situation in Problem below.

A computer supplies firm called True Disk has set up accounts for countless businesses in Dosville. True Disk sends out invoices monthly and will give discounts if payments are made within 10 days. The discounting policy is as follows: If the amount of the order for computer supplies is greater than $1,000, subtract 4 percent for the order; if the amount is between $500 and $1,000, subtract a 2 percent discount; if the amount is less than $500, do not apply any discount. All orders made via the Web automatically receive an extra 5 percent discount. Any special order (computer furniture, for example) is exempt from all discounting.

Calculate the discount amount

IF payments are made within ten days
THEN IF order amount is greater than $1,000
THEN 4 percent discount
ELSE IF the order amount is between $500 and $1,000
THEN 2 percent discount
ELSE IF the order amount is less than $500
THEN No discount
ELSE No discount
