If the markup policy for the store is assumed to be linear, find a function r = m(w) that expresses the retail price r as a function of the wholesale price w.
A music store sells a CD with a wholesale price of $5 for $11.25 and one with a wholesale price of $15.00 for $23.75.
A) r = m(w) = 1.6w + 5 C) r = m(w) = 1.6w – 5
B) r = m(w) = 5w + 1.6 D) r = m(w) = 5w – 1.6
A) r = m(w) = 1.6w + 5
