Answer

Answer:

-17%

Explanation:

Step1: Identify initial and final values

Initial value (March bill) = $120, Final value (April bill) = $100

Step2: Use percent - change formula

Percent change=$\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times100%=\frac{100 - 120}{120}\times100%$

Step3: Calculate the numerator

$100-120=-20$

Step4: Calculate the fraction

$\frac{-20}{120}\times100%=-\frac{1}{6}\times100%\approx - 16.67%$

Step5: Round to nearest whole percent

Rounding - 16.67% to the nearest whole percent gives - 17%
