Question

JJ withdraws $20 from his bank account every week for lunch. Suppose he does not make any additional deposits or withdrawals. What integer represents the change in value of JJ's bank account after nine weeks?

Answer 1

-118

Explanation:

Since he is withdrawing, the value of 20 will be negative.

And if he is withdrawing $20 over nine weeks, then it is a multiplication problem.

So,

-20 x 9 = -118
