The price of a notebook was $3.50 yesterday Today, the price rose to $3.75. How do you find the percentage increase?

Answer 1

7.1% subtract the final price by the original price to find the increase and then divide the increase by the original price.

Find the increase

# 3.75- 3.50 = .25#

Then divide the increase by the original amount

# .25/3.50= .0714285 #

To change to a percent multiply by 100 and round off to significant numbers

.0714285 = 7. 14285% or 7.1% or just 7%

Answer 2

To find the percentage increase, you would use the formula:

Percentage Increase = [(New Price - Old Price) / Old Price] * 100

Substituting the given values:

Percentage Increase = [(3.753.75 - 3.50) / $3.50] * 100

Percentage Increase = [(0.25)/0.25) / 3.50] * 100

Percentage Increase ≈ 7.14%

So, the price increased by approximately 7.14%.
