see below

Step-by-step explanation:

A percentage change is computed as follows:

percent change = ((new value) -(original value))/(original value) × 100%

For your first one, this looks like ...

percent change = ($25 -$75)/$75 × 100% = (-50/75) × 100% = -0.667×100%

percent change = -66.7%

When there are a lot of similar calculations to do, I like to use a spreadsheet. See below for the other percentage changes (rightmost column).
