Solution:
<u>We know that:</u>
<u>Simplify the equation to find the percent off:</u>
![84\% + \bold{16\%} = 100\% \space\ \space\ \space\ \ \ \ \ [Rounded]](https://tex.z-dn.net/?f=84%5C%25%20%2B%20%5Cbold%7B16%5C%25%7D%20%3D%20100%5C%25%20%5Cspace%5C%20%5Cspace%5C%20%5Cspace%5C%20%5C%20%5C%20%5C%20%5C%20%5BRounded%5D)
This means that the <u>original price</u> has decreased about 16%.
I can solve with 2 methods:
I. Because the discount is 15 % of 18 $ , the price will be (100-15=85) 85 % of 18 $
18*85/100= 15,3 $ ( the sale price)
II. The discount is 15 % of 18$
15*18/100= 2,7$ ( the discount)
then I decrease it from the regularly price
18$-2,7$=15,3 $ (the sale price)
Personally I believe the first is an easier method.
I hope you understand and you can apply this in every similary problem.
Scott has 16 more lid fulls of detergent than nikki. First you need to convert 1.5 gallons to ounces which is 192. Then divide 192 by 3 and you get 64. Then divide 192 by 4 and you get 48. So then subtract 48 from 64 and you get 16.
