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?

Question

A. -200 and - 500
B. -400 and -500
C. -100 and -800
D. -200 and -600

Answer 1

Let's represent the situation using an equation:

$800 - A - B = 0$

Solving for A and B:

$A + B = 800$

From this equation, the possible integer values for A and B are:

A. -200 and -500 ($(-200) + (-500) = 800$)
B. -400 and -500 ($(-400) + (-500) = 900$)
C. -100 and -800 ($(-100) + (-800) = 900$)
D. -200 and -600 ($(-200) + (-600) = 800$)

Therefore, the correct answer is A. -200 and -500.
