Mrs. Wilkinson's grandchildren are participating in a gift wrap sale to raise money for their
school. She decided to stock up, so she ordered 1 roll of reversible paper and 2 rolls of
metallic paper from Michelle, spending a total of $36. She also ordered 4 rolls of reversible
paper and 4 rolls of metallic paper from Ellie, which cost a total of $100. Assuming that rolls
of each type are priced the same, what is the price for each kind of paper?
