hopefully i can explain this well...think of it this way:
if wal-mart was to have a 20%-off sale on the belts, what price would they have to set on the belts so that they don't lose money (in this case, wal-mart won't sell the belts for less than $30 since they bought it at that price). try to calculate it backwards. so if you make an algebraic equation, it would be:
(assume "x" is the price you need to charge)
x - 0.20x = 30
if you calculate it, it would turn out to be...
0.80x = 30
x = 37.50
is that clear? if not, i'll try re-explaining it.
good luck! =]
