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
