Question

Basic sales tax is applicable at a rate of 10% on all goods, except books, food, and medical products that are exempt. Import duty is an additional sales tax applicable on all imported goods at a rate of 5%, with no exemptions. When I purchase items I receive a receipt which lists the name of all the items and their price (including tax), finishing with the total cost of the items, and the total amounts of sales taxes paid. The rounding rules for sales tax are that for a tax rate of n%, a shelf price of p contains (np/100 rounded up to the nearest 0.05) amount of sales tax. Write an algorithm, not code, hat prints out the receipt details for these shopping baskets

Answer 1

Items:list of goods

saleTax:tax levied on the goods

saleTax <-- 0

totalBasePrice:sum of all items basic price

totalBasePrice <-- 0

noSalesTax:set containing type of items not applicable for sales tax

procedure PrintReceipt(items,saleTax,noSalesTax)

for each item x in items

if x not in noSalesTax set

saleTaxItem(rounded to 0.05) <-- (price of x)*0.1

end

if x is imported

saleTaxItem (rounded to 0.05) <-- (price of x)*0.05 added to saleTaxItem

end

totalBasePrice <-- add price of x to totalBasePrice

print item x: price added to saleTaxItem

saleTaxTotal <-- addition of each saleTaxItem to saleTaxTotal

end

print Sales Tax: saleTaxTotal

print Total:addition of totalBasePrice and saleTaxTotal
