Step-by-step explanation:
<u>Operations With Integers</u>
We need to perform addition and subtraction to complete the answer to this problem.
Derrick first withdrew $17 from his account. Since the money is coming out from the account, it's considered as negative. Thus this operation is recorded as -$17.
The next day he deposited $12, which is considered as positive. This operation is considered as $12 or +$12.
The net operation or total change in the account is: -$17 + $12.
Subtracting and simplifying: -$17 + $12 = -$5
The total change in his account is represented by the integer -5
Mean = 74.4
Median = 83.5
Mode = 93
