A student has $−27 in their bank account. They earn some money and are able to deposit it into their account. How much money does the student need to add to their account to have a balance of $0?
A. $27
B. $54
C. $−54
D. $−27
To find the amount of money the student needs to add to their account, we need to find the difference between their starting balance of $-27 and their desired balance of $0. The amount of money they need to add is therefore $0 - (-27) = $0 + $27 = $27. Answer: \boxed{27}.
To find out how much money the student needs to add to their account to have a balance of $0, we need to calculate the absolute value of their current balance.
The absolute value of $−27 is $27.
Therefore, the student needs to add $27 to their account to have a balance of $0.
The correct answer is A. $27.
