Question

Employees of a discount appliance store receive an additional 20% off of the lowest price on an item. If an employee purchases a dishwasher during a 15% off sale, how much will he pay if the dishwasher originally cost $450?

Answer 1

The answer is $306.00

First we find the lowest price available since the employee discount is taken from it.

This 15% discount would be :

($450) x (.15) = $67.50 (.15 comes from the 15/100)

We subtract this from the original, since the $67.5 was the percent off:

(450) - (67.50) = $382.50

Now we have the lowest price, $383.50, from which we can now take the employee discount from:

(382.50) x (.2) = $76.50 (.2 comes from the 20/100)

We subtract this from the new lowest price, since the $76.50 was the percent off:

(382.50) - (76.50) = $306.00

We end up with with this as our final answer.
