amount remaining on the card.
To calculate the amount remaining on the card after a certain number of months, you can use the formula:
Remaining amount = Starting value - (Number of months after first year * Decrease per month)
Let's say we want to calculate the amount remaining on the card after 15 months. Using the given information that the starting value is $25 and the decrease per month is $2.50, we can substitute these values into the formula:
Remaining amount = $25 - (15 * $2.50)
Remaining amount = $25 - $37.50
Remaining amount = -$12.50
In this case, the remaining amount is negative, indicating that the card value has reached $0 and is now in a negative balance.
