The price of an item has risen to $174 today. Yesterday it was $120.Find the percentage increase.
To find the percentage increase, we need to calculate the difference between the new price and the old price, and then divide that difference by the old price. Finally, we multiply the result by 100 to find the percentage increase.
Difference = New price - Old price = $174 - $120 = $54
Percentage increase = (Difference/Old price) * 100 = ($54/$120) * 100
Percentage increase = 0.45 * 100 = 45%
Therefore, the percentage increase is 45%.
