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