Here's the question you clicked on:

tell whether each percent change is an increase or decrease. Then find the percent change. Round to the nearest percent. original amount: 45 new amount: 60
What do you think about this question? Any ideas?
None. My teacher hasn't taught me this yet. I know it's an increase though.
\[\%\Delta = \frac{|a - b|}{a} \times 100\] \(\%\Delta = \) Percent Change \(a = \) Old Amount \(b = \) New amount
Ook Can u use the actual numbers in that ?
Yes, that's what you're supposed to do. In this case: \(a = 45\) \(b = 60\)
Thank u. It's hard for me to understand this stuff. ok so it would be x = 45−60 ==== ×100 45 45 - 60 = -15 15 == = 3 45 3(100) = 300
\[\frac{15}{45} = \frac{1}{3}\]
ok so 1/3(100) = 33
