10) At Best Buy thay have a stereo system that sells for $1250 and is on sale for 25%

and sales tax is 34%. What is the final cost?

=$1256.25

Explanation:

The stereo sales for $1250 but is on sale at 25 %

25% is the current discount. A discount reduces the selling price.

The price after discount will be:

$1250 - (25% of 1250)

=1250 - (25/100 x 1250)

=1250-312.5

=$937.50

Add 34 % tax

= 937.5 + (34 / 100 x 937.5)

=937.5+318.75

=$1256.25
