To calculate the percent of the value of the card that has been lost, we need to find the difference between the initial value and the current value, and then express that difference as a percentage of the initial value.
The initial value of the baseball card was $11.00, and the current value is $8.00. Therefore, the difference between the initial and current values is:
$11.00 - $8.00 = $3.00
To express this difference as a percentage of the initial value, we can use the formula:
(percent change) = (|change| / original value) x 100%
Plugging in the values we get:
(percent change) = (|$3.00| / $11.00) x 100%
(percent change) = 27.3%
Therefore, the percent of the value of the card that has been lost is 27.3%, which is option B.
