Answer:
35% discount
Step-by-step explanation:
We can first find what percent of 32 20.80 is.
This can be shown by using a percent proportion.
![\frac{20.80}{32} = \frac{x}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B20.80%7D%7B32%7D%20%3D%20%5Cfrac%7Bx%7D%7B100%7D)
We can cross multiply to find the value of
.
![20.80\cdot100=2080\\\\2080\div 32 = 65](https://tex.z-dn.net/?f=20.80%5Ccdot100%3D2080%5C%5C%5C%5C2080%5Cdiv%2032%20%3D%2065)
So 20.80 is 65% of 32.
However, this is the percent of the original price. To find the discount, we have to subtract 65 from 100.
![100 - 65 = 35](https://tex.z-dn.net/?f=100%20-%2065%20%3D%2035)
So the book was on a 35% discount.
Hope this helped!
