You withdraw $14 from a bank account once per day for seven days. What integer expresses the change in value of your bank account?
The change in value of the bank account can be expressed as the sum of the seven daily withdrawals:
$14 + $14 + $14 + $14 + $14 + $14 + $14 = $98
Therefore, the change in value of the bank account is -$98.
To find the change in value of your bank account, you need to subtract the total amount withdrawn from the initial balance. Since you withdrew $14 once per day for seven days, the total amount withdrawn is $14 x 7 = $98.
So, the change in value of your bank account is -$98.
