of soda cost $0.25.
In 2015, a bottle of
soda cost $1.50.
What is the percent
increase?

Answer 1

25% increase

Explanation:

You multiply the original number (0.25) by 100.

`0.25(100)= 25`

% increase = Increase ÷ Original Number × 100. If the answer is a negative number, that means the percentage change is a decrease.
