B) the consumer price index (CPI) will almost certainly rise in 2008,even if Laguna Nigel is not included in the index,as long as tofu is included and becomes more expensive on average at the other locations.
C) the consumer price index (CPI) will likely fall (in 2008) if the average weighted price of tofu increases in the United States and the price of tofu at Safeway/Vons makes almost no difference in the CPI.
D) the consumer price index (CPI) might rise or fall (in 2008) and the price of tofu at Safeway/Vons could make a very small difference in the CPI if tofu at Safeway/Vons is included in the index.But because tofu is a relatively large portion of the entire CPI,it is most likely the CPI will rise.
