A. The percent decreases is 20%
B. The percent decreases is 25%
C. The percent decrease is 80%
D. The percent decrease is 87%

Answer 1

The percent decrease is 80%.

Answer 2

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

percentage decrease =
`(original - new)/(original) * 100`

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

`(300-60)/(300)*100\\=(240)/(300)*100\\=0.8*100\\=80`.

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