If Nick has to add m amount of money to the card, and the current balance on the card is represented by ?, the equation can be represented as:

? + m = ?

3 answers

The equation would be:

Current Balance + Amount to Add = New Balance
18.25 + m = 30
m = ?
To find the amount that Nick needs to add to the card (m), you can rearrange the equation:

18.25 + m = 30

Subtract 18.25 from both sides:

m = 30 - 18.25

m = 11.75

Therefore, Nick needs to add $11.75 to the card.
