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

450 * 0.85 * 0.8 = $______

To calculate the final amount the employer will pay for the dishwasher, we need to apply the discounts in the correct order.

First, we need to apply the 15% off discount during the sale. To calculate this, we multiply the original cost of the dishwasher ($450) by 0.15, which gives us a discount of $67.50.

Now we subtract this discount from the original cost:

$450 - $67.50 = $382.50.

Next, the employer receives an additional 20% off the lowest price. To calculate this discount, we multiply the discounted cost ($382.50) by 0.20, which gives us a discount of $76.50.

Finally, we subtract this additional discount from the discounted cost:

$382.50 - $76.50 = $306.

Therefore, the employer will pay $306 for the dishwasher after applying both discounts.
