Step-by-Step Solution

$40-8=32$

In order to determine percentages, we must make use of the two pieces of information in our possession: the total amount ( $40) and the discount (20%).This information can be inserted into the following formula:\( \frac{Price\times\text{Percentage}}{100}$ Which allows us to find the percentage of something.

We insert the given information:

$40\times\frac{20}{100}=$
$\frac{800}{100}=$

$8$

We then discover that the value of the discount is 8.

But we are not finished yet!

We need to subtract the discount from the original amount in order to determine the sale price:
$\( 40-8=32$
