Here's an easy way of understanding it:

$\displaystyle \text{original} \times 0.4 = \$ 500$

Multiplying by 0.4 is the same as 40% of.

$\displaystyle \text{original} = \$ 500 \div 0.4$ - Sep 25th 2010, 03:24 AMHallsofIvy
Or: Let x be the original price. Then the price was decreased by 60% or .6x: x- .6x= (1- .6)x= .4x= 500 and now solve by dividing both sides by .4.
