Answer 2

The single decimal multiplier is 1.26.

Explanation:

Multipliers:

For a decrease of a%, we multiply by:
`(100-a)/(100)`

For a increase of a%, we multiply by:
`(100+a)/(100)`

For consecutive changes, we multiply the multipliers.

Increase of 5%

Multiply by
`(100+5)/(100) = (105)/(100) = 1.05`

Increase of 20%

Multiply by
`(100+20)/(100) = (120)/(100) = 1.2`

Consecutive:

1.05*1.2 = 1.26

The single decimal multiplier is 1.26.
