so percent means parts out of 100
35% means 35/100=3.5/10=0.35/1=0.35
35% off means find 35% and subtract that
so if she bought 124.60 and subtracted 35%
so then we do
124.6 times 0.35=how much off=43.61
so subtract
124.6-43.61=80.99
another hack is 124.60=100% and 100%-35%=65% so just find 65% of 124.6
answer is end cost=$80.99
