Answer 1

`\%Increase = 33.25\%`

Explanation:

Given

Initial = 12

Final = 15.99

Required

Determine the percentage increment

This is calculated as thus:

`\%Increase = (Final - Initial)/(Initial) * 100\%`

Substitute values for Initial and Final

`\%Increase = (15.99 - 12)/(12) * 100\%`

`\%Increase = (3.99)/(12) * 100\%`

`\%Increase = (3.99* 100\%)/(12)`

`\%Increase = (399\%)/(12)`

`\%Increase = 33.25\%`

Hence, the percentage increment is 33.25%
