Anya withdraws $14 from her bank account once each day for seven days. What integer represents the change in the amount in the account? Find the integer that would represent the change in the amount in the account if Anya deposits $14 into her bank account once each day for seven days. Explain the difference between the integer for the withdrawals and the integer for the deposits.
+1090 If she withdraws $14 from her bank account, then her account balance decreases by $14, so the change to the balance is -$14. Multiply -14 times 7 (which will be a negative product) to get the total change to the amount in her account in the first scenario.
Adding $14 is very similar, the only difference being her account balance increases by $14, so the change to the balance is $14. Multiply this by 7 to get the total change to the amount in her account in the second scenario.
Hopefully the difference between the withdrawal and deposit is clear from the earlier explanation.
