Answer:
the change in quantity divided by the quantity.
Explanation:
Percentage Change in any variable is calculated by :
(Change in Variable / Variable old value ) x 100 ; where
Change in Variable = Variable New Value - Variable Old Value
Example : If Price change from 10 to 15
Percentage change in price = (Change in Price / Old Price) x 100
= [(15-10) / 10] x 100
= [ 5/10 ] x 100
= 50%
