Answer:
A price increase of 1% will reduce quantity demanded by 4%
Explanation:
If the price elasticity is 4 then, this demand is highly responsive to changes in price.
So it will decrease by more than the price increase.
we must remember that the price-elasticity is determinate  like:
↓QD / ΔP   = price-elasticity
if the cofficient is 4 then a 1% increase in price:
↓QD / 0.01 = 4
↓QD = 0.04
Quantity demanded will decrease by 4%
