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!
