employment. I think I will learn how to properly do
research and find the price of my favorite candy bar
when I get to be 63. Based on current and projected
inflation rates, my skills on calculating linear
equations, and my experience using Microsoft Office
Excel program, how much will a Hershey’s Candy
Bar cost in the year 2062 --when I am about to retire?

Introduction paragraph on Name Brand product.
Answer: When I got this project, I thought it would
be easy to find out the price of a Hershey candy bar
and what it will cost in 2062. The Name Brand
Product Hershey’s really interested me because I like
to eat chocolate. I think this will be another useless
project that the teachers makes me do. Problem
statement: How much will a Hershey’s candy bar cost
in the year 2062.
