Asked by Emma
The regular price of a sleeping bag is
$39.95. It is on sale for 20% off.
There is a 13% sales tax. The discount
is usually applied before the tax is
added. Suppose the tax is calculated
first. Would the total cost be more or
less in this case? Explain.

discount first: 29.95 * 0.80 * 1.13
tax first: 29.95 * 1,13 * 0.80
since multiplication is commutative, it gives the same answer.
by using the discount first, the amount taxed is less
by taxing first, the discount is more
