Answer:155.56%.
Step-by-step explanation:To find the percentage increase, we need to calculate the difference between the two prices and divide it by the original price, then multiply by 100 to express the answer as a percentage.
Percentage increase = (New price - Original price) / Original price * 100
Percentage increase = (459 - 180) / 180 * 100
Percentage increase = 279 / 180 * 100
Percentage increase = 155.56%
So the price of the item increased by 155.56%.
