9-9 6 th grade math Computing Discounts

Objective To find discount and sale price Why? To know how much you should pay for something that is on sale (at a discounted price). Remember discount prices are rounded down to the nearest cent. “The store managers don’t want to lose too much of his/her money!”

California State Standards NS 1.4 : Calculate given percentages of quantities and solve problems involving discounts at sales …

Vocabulary Discount – To receive a lessened amount off of a set price 25% discount would be ¼ off of a regular price item

How to Compute Discounts 1) Multiply the rate to the subtotal 2) Subtract the amount from the subtotal for the new total. Round down to the nearest cent. 3) Check your work 25% off $ What is the new price?.25 x = $ – 3.99 = $12

Try It! Find the discount and the sale price. 1)Regular price: $200; rate of discount: 10% 2)Regular price: $56; rate of discount: 25% 3)Reg’l price: $66; rate of discount: 33 ⅓% 4)Reg’l price: $29; rate of discount: 20% (for 2 items) 1)$200 x.10 = – 20 = $80 2) $56 x.25 = – 14 = $42 3) $66 x.3333 = – = $ ) $29 x 2 = x.20 = – = $46.40

Objective Review To find discount and sale price Why? You now know how much you should pay for something that is on sale (at a discounted price). Remember discount prices are rounded down to the nearest cent. “The store managers don’t want to lose too much of his/her money!” You can multiply a price by the rate of discount to find the amount of discount, then you subtract the amount from the price to find the sale price.
