Question

The price of a cup of coffee has risen to $2.45 today. Yesterday's price was $2.15. Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answer 1

13.9535% increase, so yeah, like, 14%

Explanation:

Answer 2

14%

Explanation:

To find the percentage change of any two amounts you just need this formula: (new - old) ÷ old

New price = $2.45

Old price = $2.15

2.45 = 2.15 = 0.3

0.3 ÷ 2.15 = 0.139534883721

This would make the percentage increase = %13.9534883721

But the question wants it rounded to the near tenth, so it's %14
