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.
[tex]\frac{20.80}{32} = \frac{x}{100}[/tex]
We can cross multiply to find the value of [tex]x[/tex].
[tex]20.80\cdot100=2080\\\\2080\div 32 = 65[/tex]
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.
[tex]100 - 65 = 35[/tex]
So the book was on a 35% discount.
Hope this helped!
