Rumba Dance Hall has offered to buy from Muy Bueno Bakery 100 of its chocolate cakes for $26 each. No variable selling costs would need to be paid, but special packaging of $140 will have to be added. Normally, Muy Bueno sells its cakes at $36 each. Its costs per cake are materials, $11; direct labor, $8; variable factory overhead, $2; fixed factory overhead, $3; and variable selling costs, $3. How much differential profit or loss will Muy Bueno make if it accepts this offer

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?
