The percentage of decrease 32.
Step-by-step explanation:
Given: Rowena’s monthly gasoline bill dropped from $83.75 last month to $56.95 this month.
Here we use formula to find the percentage of decrease.
Percentage of decrease =![\frac{Decrease amount}{Original amount} *100](/tpl/images/0311/9280/27e38.png)
Decrease amount = $83.75 - $56.95 = $26.80
Original amount = $83.75
Percentage of decrease =![\frac{26.80}{83.75} *100](/tpl/images/0311/9280/ad65f.png)
= 0.32*100
= 32%
So the percentage of decrease 32.
