@jigglypuff314 plz help :D...I opened new one so I can give u medal... The original price of a watch was $109. It was on sale for $100.28. What was the discount rate?

jigglypuff314 (jigglypuff314):

discounted was how much it was subtracted from 100% so do (discounted amount) divided by (original price) = ? then do 1.00 minus (number you get) = ?

OpenStudy (rebeccapink6398):

?

jigglypuff314 (jigglypuff314):

(discounted amount) = 100.28 (original price) = 109 so (discounted amount) divided by (original price) = ?

OpenStudy (rebeccapink6398):

8.72?

jigglypuff314 (jigglypuff314):

??? 100.28 divided by 109

OpenStudy (rebeccapink6398):

0.92!

jigglypuff314 (jigglypuff314):

yes :) then do 1.00 minus 0.92 = ?

OpenStudy (rebeccapink6398):

0.08?

jigglypuff314 (jigglypuff314):
