In US, the percent change in the annual total MSW recycled will be "0.5% in 50 years".

MSW (Municipal Solid Waste)

According to the question,

Number of years = 1960 to 2000

In 2010, total % of MSW recycled = 33

In 1960, total % of MSW recycled = 8

We know the formula,

→ The % change throughout the annual total MSW recycled

= [tex]\frac{Total \ percentage \ in \ 2010- Total \ percentage \ in \ 1960}{No. \ of \ years}[/tex]

By substituting the values,

= [tex]\frac{33-8}{2010-1960}[/tex]

= [tex]\frac{25}{50}[/tex]

= 0.5 %

Thus the approach above is right.
