Eastland College

  

Eastland College is concerned about the rising price of textbooks
that students must purchase. To better identify the increase
in the price of textbooks, the dean asks you, the
Economics Department’s star student, to create an index of
textbook prices. The average student purchases three English,
two math, and four economics textbooks. The prices of these
books are given in the accompanying table.
a. Create the price index for these books for all years with a
