The percentage change is always 100*(new-old)/old provided the old is non-negative.
If the original quantity is greater than the new quantity, the percentage change will be negative - no big deal.
Unit elastic
When the percentage change in price is equal to the percentage change in quantity demanded then demand is said to be unit elastic. There are 3 kinds of price elasticity of demand.
It will be very sensitive to price change. A change in the price will change the quantity supplied by a factor greater than 1. ps: Price elasticity of supply= (% change in quantity supplied)/(% change in price)
a change in quantity supplied is the result of
it means that price is elastic. Price elastic means that a little change in the price will cause a substantial change in the quantity demanded.
change of any quantity divided by its original quantity

Percent Increase
The quantity is decreasing.
Yes, percent change can be negative. A negative percent change indicates a decrease in quantity or value from the original amount. It is calculated by comparing the final value to the initial value.
