Answer:
The answer is
[tex]67\%[/tex]
Step-by-step explanation:
To find the percentage increase we use the formula
[tex]Percentage \: change = \frac{change}{original \: \: quantity} \times 100\%[/tex]
From the question
The original value = 12
To find the change we subtract the smaller value from the larger one
That's
Change = 20 - 12 = 8
So the percentage increase is
[tex] \frac{8}{12} \times 100 \%\\ = \frac{2}{3} \times 100\% \\ = 66.67\%[/tex]
We have the final answer as
[tex]67\%[/tex] to the nearest whole number
Hope this helps you
