A stackable storage rack holds 22 dvds and costs $21. How much would it cost to buy enough racks to hold 127 dvds?

((floor((127/22) + 0.5)) * 21) = $126
more generally ...
NDVD = number of dvd's
RHOLDS = number of dvd's held per rack
PDVD = price of a single dvd
CRACKS = cost for racks
CRACKS = ((floor((NDVD/RHOLDS) + 0.5)) * PDVD)
