Oh sure. You take 10% and then multiply it by 2. 
10% of 1448.74 is (rounded) 145, times 2 is 290. 
/edit: shh! don't tell him I told you his secret! |
20%
*off* 1448.74 would be 80%, which would change to formula to:
1448.74 / 10 = 144.874
144.874 * 8 = 1158.992
It's a little harder calculation but us programmers are known for taking shortcuts anyway.
Then again, I can come up with an answer from my head in a split second too, nobody said it had to be right.
