Answer:
10.5%
Step-by-step explanation:
Prices rose in 1 year = 30% and came down by next year by 15%.
Percentage change formula when x is positive and y is negative,
=> {x - y - (xy/100)}%
Here, x = 30% and y = 15%
Change in percentage will be,
=>(30 - 15 - (30 * 15)/100}
=> (15 - 4.5)
=> 10.5
Hence, price change percentage is 10.5%
Hope it helps!
