You withdraw ​$14 from a bank account once per day for seven days. What integer expresses the change in value of your bank​ account?

1 answer

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.
