A concrete batch calls for the following quantities per cubic yard of concrete, based on saturated surface-dry conditions of the aggregate. Determine the required weights of each solid ingredient and the number of gallons of water required for a 6.5-cy batch. Also determine the wet unit weight of the concrete in pounds per cubic foot (cement, 3,666 lbs; fine aggregate, 9,230 lbs; coarse aggregate, 11,960 lbs; water, 1,841 lbs; and wet unit weight, 152 pcf).

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.
