If the required rate of return on a bond (rd) is greater than its coupon interest rate and will remain above that rate, then the market value of the bond will always be below its par value until the bond matures, at which time its market value will equal its par value. (accrued interest between interest payment dates should not be considered when answering this question.)
a. true
b. false

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?
