What is the percentage increase from 5 to 7?
A. 20%
B. 25%
C. 40%
D. 60%
Correct Answer: C) 40%
Explanation:
To find the percentage increase, we can use the formula:
(new value – old value) / old value x 100.
In this case, (7 – 5) / 5 x 100 = 0.4 x 100 = 40%.
Therefore, the percentage increase from 5 to 7 is 40%.
