Just do .32x=64 and then divide by .32 to get x=200 as the price before discount.
discount=amount saved
so discount/original=discount/original
32%/100%=$64/?
find ?
32/100=64/?
multiply both sides by 100*? (aka cross multiply)
32*?=64*100
32?=6400
divide both sides by 32
?=200
the price without discount is $200
