r=m(w)=1.26w=5
I am not sure, but I got help on this question
A music store sells a CD with a wholesale price of $6 for $10.50 and one with a wholesale price of $14.00 for $20.50. 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.
