Answer 1

Answer:

$\%Increase = 33.25\%$

Step-by-step explanation:

Given

Initial = 12

Final = 15.99

Required

Determine the percentage increment

This is calculated as thus:

$\%Increase = \frac{Final - Initial}{Initial} * 100\%$

Substitute values for Initial and Final

$\%Increase = \frac{15.99 - 12}{12} * 100\%$

$\%Increase = \frac{3.99}{12} * 100\%$

$\%Increase = \frac{3.99* 100\%}{12}$

$\%Increase = \frac{399\%}{12}$

$\%Increase = 33.25\%$

Hence, the percentage increment is 33.25%
