we know that
Using the original score as the basis
If Misha increased her test score from [tex] 60 [/tex]% to [tex] 80 [/tex]%
then
the increase variation is equal to
[tex] 80 [/tex]%-[tex] 60 [/tex]%=[tex] 20 [/tex]%
to find the approximate percent increase of Misha's test score we apply a rule of three
if [tex] 60 [/tex]%--------------> represents [tex] 100 [/tex]%
[tex] 20 [/tex]%----------------->x
[tex] x=20*100/60 [/tex]
[tex] x=33.33[/tex]%
therefore
the answer is
the approximate percent increase of Misha's test score is [tex] 33 [/tex]%
