In 1984 the average American ate 55.7 lbs. of chicken.  This was 
2.8 lbs. more than the average in 1982.  What was the percent of 
increase in chicken consumption from 1982 to 1984?

Hi there! The percent increase is how much something increased in 
comparison to the original amount.

So if I sold something for $25 which I'd bought for $20, making a $5
profit, the percent increase in price would be 

$5      1    25   
---  =  -  = --- = 25 percent
$20     4    100


Does that make sense? Can you apply the same method to your problem?
