Question

Rachel withdraws ​$18 from the bank account once each day for six days. What integer represents the change in the amount in the​ account? Use a pencil and paper. Find the integer that would represent the change in the amount in the account if Rachel deposits ​$18 into her bank account once each day for six days. Explain the difference between the integer for the withdrawals and the integer for the deposits.

Answer 1

Answer:

-108

108

Step-by-step explanation:

Since it is withdrawing, we are taking away -$18 every day for 6 days.

(-18)*6 = -108

Since it is deposits, we are adding to the amount in her account, +$18 for 6 days.

18*6 = 108

The difference is that one is taking away and one is adding each day, resulting in negative or positive change.
