Answer 1

To find percentage decrease of something, we use this general formula:

percentage decrease = $\frac{original - new}{original} * 100$

Plugging in original value of 300 and new value of 60 will give us:

$\frac{300-60}{300}*100\\=\frac{240}{300}*100\\=0.8*100\\=80$.

So we have a 80% decrease. Answer choice C is correct.
