Answer 1

The percent change in the annual total municipal solid waste (MSW) recycled from 1960 to 2000 in the United States is 1040%.

Step-by-step explanation:

To calculate the percent change in the annual total municipal solid waste (MSW) recycled from 1960 to 2000, we will use the formula:

Percent Change = ((New Value - Old Value) / Old Value) × 100%

Using the values from the table for 1960 and 2000, which are 5 million metric tons and 57 million metric tons respectively, the calculation is as follows:

Percent Change = ((57 - 5) / 5) × 100%

Percent Change = (52 / 5) × 100%

Percent Change = 10.4 × 100%

Percent Change = 1040%

The percent change in the annual total MSW recycled from 1960 to 2000 in the United States is 1040%.
