Javier has been saving for a digital camera. he finds one on sale for $67.50. it usually costs $90.00. what is the percent of discount?

Original price of camera = 90
Price of camera after discount = 67.50
Discount amount = (90-67.5)
                            = 22.5

so the percentage of discount = (22.5 / 90) * 100
                                                = 25 %

The price decreased by 40 percent㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒∞㏒∞㏑⊕⊆⊂ф
