Question

Help help me plzzzzzzz

Answer 1

1). 25% percentage increase

2). 75% percentage decrease

Explanation:

1.

`Percent \: of \: change = (amount \: of \: change)/(original \: amount) * 100\%`

Amount of change =30-24=6

Original amount = 24

`Percent \: of \: change = (6)/(24) * 100\%`

`Percent \: of \: change = (1)/(4) * 100\% = 25\%`

This means there is a percentage increase of 25%

2.

Amount of change =4-16=-12

Original amount=16

`Percent \: of \: change = ( - 12)/(16) * 100\%`

`Percent \: of \: change = - (3)/(4) * 100\% = - 75\%`

This means there is a percentage decrease of 75%
