Answer:

D. -17%

Step-by-step explanation:

The change from March to April is (April - March) = (100 -120) = -20. As a fraction of the March bill, that is ...

-20/120 = -1/6

As a percentage, that change is ...

-1/6 × 100% ≈ -16.667% ≈ -17%

The electric bill changed by about -17% from March to April.

_____

<em>Additional comment</em>

Water went up 4%; groceries went up about 14%, and restaurant changed by -15%.

The percentage change is found by ...

% change = ((new amount)/(original amount) -1) × 100%

Above, we have rearranged this to ...

% change = ((new amount) -(original amount))/(original amount) × 100%
