The coach for the cheerleaders is shopping for uniforms for eight new
cheerleaders.
Sports Discount is offering a 20%
discount on each uniform. Each
uniform is priced at $68.00. A 7%
sales tax will be applied to the
discounted price.
The same uniforms are also available
on Cheerleading for Less web site for
$56.50. The tax on the uniforms is
8.5% plus a total shipping fee of
$29.99 for the entire order.
What is the difference in the total
costs of the 8 new uniforms between
the two stores?
