Question

Find each percent increase round to the nearest percent from 13 friend to 14 friends

Answer 1

7.69% is the correct answer. 14-13= 1/13 * 100%

Answer 2

from 13 friends to 14 friends. The number of friends is increased by 1.

To get the percentage of increase:

(14 - 13) / 13 = 1 / 13 = 0.0769 * 100% = 7.69%

The increase of 1 friend is equivalent to 7.69% increase.

13 is the basis. It is the 100%
1 is the increase. It is the 7.69%
14 is the total number of friends. It is the 107.69% = 100% + 7.69%
