Let
v---------> the original value of the baseball card
we know that
[tex]36=80v[/tex] ------> equation to find the original value of the baseball card
solve for v
Divide both sides by [tex]80[/tex]
[tex]v=36/80[/tex]
[tex]v=\$0.45[/tex]
therefore
the answer is
the original value of the baseball card is [tex]\$0.45[/tex]
