To find out how much the student had before purchasing the jacket, we need to add the cost of the jacket to the amount of money they currently have in their bank account.
So, to calculate this, we can subtract the current balance of -$24 from the cost of the jacket, $128:
$128 - (-$24) = $128 + $24 = $152
Therefore, the student had $152 before purchasing the jacket.
To find out how much the student had before purchasing the jacket, we can use a simple equation:
Amount before purchasing the jacket - cost of the jacket = remaining balance
Let's say the amount before purchasing the jacket is represented by the variable "x".
We know that the cost of the jacket is $128, and the remaining balance in the student's account is −$24.
So, the equation becomes:
x - $128 = −$24
To solve for x, we need to isolate the variable x on one side of the equation.
Adding $128 to both sides of the equation:
x - $128 + $128 = −$24 + $128
x = $104
Therefore, the student had $104 before purchasing the jacket.
