Answer:

See explanation and example below.

Step-by-step explanation:

To find percent increase you must know the original amount and the new amount. Then use the formula below:

percent increase = (new amount - old amount)/(old amount) × 100%

Example:

A book used to cost $10. Then the price increased to $12. What is the percent increase?

Given information:

old amount = $10

new amount = $12

Percent increase formula:

percent increase = (new amount - old amount)/(old amount) × 100%

Apply the given information to the formula:

percent increase = ($12 - $10)/($10) × 100%

percent increase = $2/$10 × 100%

percent increase = 0.2 × 100%

percent increase = 20%

Answer: The percent increase from $10 to $12 is 20%.

Answer:

Increase = Increase / The original Number * 100

Don't worry I gotchu!

You basically divide the amount that is progressing, i.e, or that is, the increase of the number by the original number and then multiply by 100. SO thats how you find the percent of increase! Sry if i stated another formula but i think it is the right one. sry if i am wrong :(
