Suppose Marisol has $800 in her savings account. She withdraws A dollars from her account. Deciding that this is not enough, she makes another withdrawal of B dollars. The amount of money left in her savings account now equals zero. What integers represent the withdrawals from her account?
The total amount of money withdrawn from Marisol's account can be represented by the equation A + B = 800. Since the amount left in her account is zero, the equation can also be written as A + B = 800.
Therefore, the integers representing the withdrawals from her account are A = $400 and B = $400.
