Question

The current value of a baseball card is 80 times its original value vv (in dollars). The baseball card is worth $36. Write and solve an equation to find the original value of the baseball card.

Answer 1

36 / 80 = original value 
0.45

Answer 2

Let

v---------> the original value of the baseball card

we know that

$36=80v$ ------> equation to find the original value of the baseball card

solve for v

Divide both sides by $80$

$v=36/80$

$v=\ 0.45$

therefore

the answer is

the original value of the baseball card is $\ 0.45$
