If discount is 25%, you pay 75%. .75x = 40 Divide both sides by .75    x = $53.33 .95x = 57 Divide both sides by .95   x = $60.00 .20x = 90 Divide both sides by .20    x = $450.00 .85x = 146.54  Divide both sides by .85     x = $172.40 (change)/(original) * 100 = % (60 - 45)/60  * 100 = 25% (82-62.60)/82 * 100 = 23.7% , 23.66%, 24% (depends on rounding) (95-61.75)/95  * 100 = 35%
