I get a 10% discount at work
I also have a way to buy gift cards at 6% off
So say an item is $100, I can get it for $90, but then I can buy $90 gift cards for just $84.60, so the $100 item only costs me $84.60.
How can I easily calculate the cost of an item without having to do two steps?
I thought it would be (cost of item) * 0.84 (16% off) but obviously that isn't correct.

Is that WWF wrestler Kevin Nash? Why does he look so upset?

Use this: [math] D=C \cdot 0.846 [/math]
C is the cost of the item, D is the discounted price
after accounting for two different discounts (what you pay).
The 0.846 is basically 1 - 0.154, which almost fits your
estimate of 16% off total discount (15.4%)
Test: Let C = 100
Then, D = 100 (0.846) = 84.6
