Answer: There is overall percentage increase is 80% from 2007 through 2009.
Step-by-step explanation:
Let the total games won in 2007 be 100
Percentage of more games won in 2008 = 20%
Number of games won in 2008 will be given by
[tex]\frac{100+20}{100}\times 100\\\\=\frac{120}{100}\times 100\\\\=120[/tex]
Percentage of more games won in 2009 = 50%
Number of games won in 2009 will be given by
[tex]\frac{100+50}{100}\times 120\\\\=\frac{150}{100}\times 120\\\\=1.5\times 120\\\\=180[/tex]
Overall increase from 2007 through 2009 is given by
[tex]180-100\\\\=80[/tex]
Overall percentage increase from 2007 through 2009 is given by
[tex]\frac{Difference}{Original}\times 100\\\\=\frac{80}{100}\times 100\\\\=80\%[/tex]
Hence, there is overall percentage increase is 80% from 2007 through 2009.
