Answer:
Percentage of increase = 16%
===============================================
Step-by-step explanation:
Let the price of an item ⇒ x
When the price of the item increased by 45%, the price will be ⇒ 1.45 x
Then dropped by 20%
So, the final price will be ⇒ (1 - 0.2) * 1.45x = 0.8 * 1.45 x = 1.16 x
By comparing between the original price and the final price
The difference = 1.16 x - x = 0.16x
Percentage of increase = [tex]\frac{1.16x}{x} *100=16[/tex]%
