Percent change = 100*(New value-Old Value)/Old Value
*

P=146%
Note: I wrote out the percent change this way to show that only the values are important, the billions portion (1,000,000,000) cancel each other out in the numerator and the denominator. It's easier to avoid mistakes entering all those zeros in a calculator.
