Answer:

1). 25% percentage increase

2). 75% percentage decrease

Step-by-step explanation:

$Percent \: of \: change = \frac{amount \: of \: change}{original \: amount} \times 100\%$

Amount of change =30-24=6

Original amount = 24

$Percent \: of \: change = \frac{6}{24} \times 100\%$

$Percent \: of \: change = \frac{1}{4} \times 100\% = 25\%$

This means there is a percentage increase of 25%

Amount of change =4-16=-12

Original amount=16

$Percent \: of \: change = \frac{ - 12}{16} \times 100\%$

$Percent \: of \: change = - \frac{3}{4} \times 100\% = - 75\%$

This means there is a percentage decrease of 75%
