Answer:
The multiplier for a 25% increase is 1.25.
The multiplier for a 18% decrease is 0.82.
The multiplier for a 39% increase is 1.39.
The multiplier for a 94% decrease is 0.06.
Explanation:
The multiplier for a increase of a% is 1 + a/100.
The multiplier for a decrease of b% is 1 - b/100.
25% increase:
1 + 25/100 = 1 + 0.25 = 1.25
The multiplier for a 25% increase is 1.25.
18% decrease:
1 - 18/100 = 1 - 0.18 = 0.82
The multiplier for a 18% decrease is 0.82.
39% increase:
1 + 39/100 = 1 + 0.39 = 1.39
The multiplier for a 39% increase is 1.39.
94% decrease:
1 - 94/100 = 1 - 0.94 = 0.94
The multiplier for a 94% decrease is 0.06.
