USING EXTERNAL PRICE INDEXES-PROBLEM 1 In June 2012, a buyer entered into a three-year agreement with a supplier that provides plastic water pipe. Among other things, this agreement features fixed pricing over the life of the agreement. It is now March 2015, and the agreement with this supplier is up for review and possibly renewal. While the supplier's over- all performance has been excellent, the supplier has already indicated it intends to seek a 3% price increase to cover what it calls escalating costs. The time has come to start thinking about renewing this contract. Please answer the following! questions using the data in Table 10.1.
