Question

Find the percent of change. Original: 80, new: 64

Answer 1

Hi there!

To find the percent of change we can use the following formula:
$\frac{new - old}{old} \times 100\%$

Let's fill in our data
$\frac{64 - 80}{80} \times 100\% =$

Subtract
$\frac{ - 16}{80} \times 100\% =$

Divide
$- 0.2 \times 100\%$

And finally multiply
$- 20\%$

Hence, the percent of change is negative 20%.
