Assume we have a simplified banking system in balance-sheet equilibrium. Also assume that all banks are subject to a uniform 10 percent reserve requirement and checkable deposits are the only form of money. A commercial bank receiving a new checkable deposit of $100 would be able to extend new loans in the amount of:

Four key marketing decision variables are price (p), advertising (a), transportation (t), and product quality (q). consumer demand (d) is influenced by these variables. the simplest model for describing demand in terms of these variables is: d = k – pp + aa + tt + qq where k, p, a, t, and q are constants. discuss the assumptions of this model. specifically, how does each variable affect demand? how do the variables influence each other? what limitations might this model have? how can it be improved?
