To find out how much Hugh spent from using checks, you would first add up his amounts. This looks like $20 + $20 + $12 + $20 + $12 + $42, which equals $126. However, since this is money that Hugh spent, it is a negative value to his bank account, making the number -$126.
Next, Hugh deposited $57 into his account. This is a positive value, and it should be added to the -$126. This looks like: -$126 + $57 = -$69.
Finally, Hugh was charged $15 by his bank. This is a negative value, so it will be subtracted from the current -$69 change. This looks like: -$69 - $15 = -$84. -$84 is the final answer, and represents the total change in Hugh's bank account. Hope this helps!
