    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

    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
