A retailer offers a rewards program to its customers awarding point based on each recorded purchase as follows:

For Every dollar Spend over $50 on the transaction, the customer receives one point. In addition, for every dollar spent over $100, the customer receives another point.

Ex: for a $120 purchase the customer receives 90 points (((120 - 50) * 1) + ((120 - 100) + 1))
