He consumer price index (cpi) is a measure of the change in the cost of goods over time. if 1982 is used as the base year of comparison in some country (cpiequals100 in 1982), then the cpi of 208 in 2006 would indicate that an item that cost $ 1.00 in 1982 would cost $ 2.08 in 2006 in this country. it is known that the cpi in this country has been increasing at an approximately linear rate for the past 30 years. a. use this information to determine a linear function for this data, letting x be the years since 1982. b. based on your function, what was the cpi in 2000? compare this estimate to the actual cpi of 184.6 for this country. c. how is the annual cpi changing?

For example, the upper right cell shows that if expresso advertises and beantown doesn't advertise, expresso will make a profit of $15 million, and beantown will make a profit of $2 million. assume this is a simultaneous game and that expresso and beantown are both profit-maximizing firms. if expresso decides to advertise, it will earn a profit of $ million if beantown advertises and a profit of $ million if beantown does not advertise. if expresso decides not to advertise, it will earn a profit of $ million if beantown advertises and a profit of $ million if beantown does not advertise. if beantown advertises, expresso makes a higher profit if it chooses . if beantown doesn't advertise, expresso makes a higher profit if it chooses . suppose that both firms start off not advertising. if the firms act independently, what strategies will they end up choosing? expresso will choose to advertise and beantown will choose not to advertise. expresso will choose not to advertise and beantown will choose to advertise. both firms will choose to advertise. both firms will choose not to advertise.
