Introduction: Product suppliers $($also known as vendors$)$ offer rebate programs for certain categories of products they sell. The supplier will give you a calculated amount of money back based on the quantity of items or total purchase value of products you have purchased from that category. Rebate programs are used to encourage people to keep making purchases from the same supplier, so they can get more money back. For example, if I purchased $$50,000$ worth of products, and earned a $2\%$ rebate, I would receive $$1000$ back as a rebate. Note: The values used in this exercise are for demonstration purposes only and do not necessarily reflect actual customer purchase volumes, expenditures, or rebate percentages. Part A: Use the following information to calculate the value of four rebate programs and make some assessments about their value. Rebate Conditions: $$ Supplier A $$ Invoices qualify for the rebate program if the invoice date is within the program timeframe. $$ Supplier B $$ Invoices qualify for the rebate program if the payment date is within the program timeframe. $$ Invoices paid late do not qualify for rebates. $$ An invoice will earn rebates for every program to which it applies $($can earn rebates from more than one program$).$ For programs with levels, the percentage from the highest level reached will be applied to the total value of purchases on all included invoices. $$ Rebates only apply to invoices in the specified categories for each program.
