You withdraw $15 from a bank account once per day for four days. What integer expresses the change in value of your bank account?
To calculate the change in value of your bank account, we need to consider the withdrawals.
Since you withdrew $15 once per day for four days, the total amount withdrawn can be calculated by multiplying the withdrawal amount by the number of days:
Total amount withdrawn = $15 x 4 = $60
Since you withdrew money, the change in value of your bank account would be negative. Therefore, the integer that expresses the change in value of your bank account would be -$60.
