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?

Realize this, if a person gets 20% off then they have to pay 80% of the original price.
Given this we can figure out that just given the sale price of 15%off they would have to pay $382.50- 450*.85 (they get 15% off so they pay 85%)
But we know that they also get an additional 20% off (meaning they pay 80% of the lowest price). So we take out sale price 382.50 and mulitply by 80% to get $306.

If the dishwasher costs $450, and it is 15% off, then you would pay 85% of the price (100%-15% = 85%)
$450 * 0.85 = $382.50
Now, the employee gets another 20% off that price, so the employee would pay 80% of $382.50:
$382.50 * 0.80 = $306
The employee would pay $306 for the dishwasher.

The sale price is $450 - 15%.
The staff sale price is ($450 - 15%) - 20%
= $450 * 0.85 * 0.8
= $306.

Original price = 450
15% off sale
price (after 15% off) = 450 * .85 = 382.5
Price (after 20%off employee discount)
= 382.5 * (.80) = 306

The answer is .8 x .85 x 450.
The answer is $306.

(450 * (1-.15)) * (1-.2) = 306

450x.15=67.5
450-67.5=382.5
382.5x.20=76.5
382.5-76.5=$306.00
