Task

 

W Mart, a new retail chain, has announced a discount on the total sale amount, in a single transaction, using the following scheme.

 

 

Table 1: Discount on Sale Amount
Total Sale Amount Discount on this sale amount
Less than $100 0%
From $100 up to less than $500 10% for each dollar over $100
From $500 up to less than $1,000 $40 PLUS 20% of the total sale amount over $500
From $1,000 up to less than $2,000 $140 PLUS 30% of the total sale amount over $1,000
$2,000 and above $440 PLUS 40% of the total sale amount over $2,000

 

That is, if the total sale amount is $100 then the discount will be $0. However, if the total sale amount is $101 then the discount will be $0.10. If the total sale amount is $500 then the discount will be $40, but if the total sale amount is $501 then the discount will be $40.20.

W Mart keeps track of a customer through a unique customer ID. W Mart gives one reward point for every $100 spent irrespective of the number of transactions. The points accumulate over the time for a customer for his/her purchases. Finally, for each 100 reward points it gives an additional discount of $10 on a purchase over $10 in a transaction.
