A recycling bin contained 40 pounds of plastic in October and 50 pounds of plastic in November. By what percentage did the amount of plastic increase from October to November?
Question 6 options:
10%
25%
20%
80%
20%
To calculate the percentage increase, we first need to find the difference in weight between November and October: 50 pounds - 40 pounds = 10 pounds.
Then, we divide the difference by the starting weight in October and multiply by 100 to get the percentage increase: (10 pounds / 40 pounds) x 100 = 25%.
Therefore, the amount of plastic increased by 25% from October to November.
