The current value of a baseball card is 50 times its original value v (in dollars). The baseball card is worth $62. Write and so
ehidna [41]
If the current value of the baseball car is 50 times its original value, its original value will be its current value divided by 50.

Let v represent the current value of the baseball card. We know form our problem that $62 is 50 times the original value, v, of the baseball card, so translating this statement to an equation we get:
62=50v
v= \frac{62}{50}
v=1.24

We can conclude that the original value of the baseball card was $1.24.
