Answer:
1). 25% percentage increase
2). 75% percentage decrease
Step-by-step explanation:
1.
[tex]Percent \: of \: change = \frac{amount \: of \: change}{original \: amount} \times 100\%[/tex]
Amount of change =30-24=6
Original amount = 24
[tex]Percent \: of \: change = \frac{6}{24} \times 100\%[/tex]
[tex]Percent \: of \: change = \frac{1}{4} \times 100\% = 25\%[/tex]
This means there is a percentage increase of 25%
2.
Amount of change =4-16=-12
Original amount=16
[tex]Percent \: of \: change = \frac{ - 12}{16} \times 100\%[/tex]
[tex]Percent \: of \: change = - \frac{3}{4} \times 100\% = - 75\%[/tex]
This means there is a percentage decrease of 75%
