Answer:
0.25
Explanation:
From the information given, you can say that the current value of a baseball card is equal to 60 multiplied for its original value and the equation is:
c=60v, where: c is current value and v is original value
Now, you can replace the current value with 15 that is the value of the baseball card and solve for v:
15=60v
v=15/60=0.25
According to this, the original value of the baseball card is 0.25.
