Eric has been working to conserve energy around his home. His electric
bill last month was $125, while his bill this month was $98. What is the
percent decrease in his electric bill over the past month?

Respuesta :

Answer:

21.6%

Step-by-step explanation:

Divide the previous bill by the current bill to find what percentage the current bill is of the previous bill

98/125 = 0.784

Subtract the decimal from 1 to change it from what the percentage is of the previous bill to how much the bill decreased by

1 - 0.784 = 0.216

Multiply by 100 to change the decimal into a percentage

0.216 × 100 = 21.6

21.6%
