D Correct answer
Explanation

The correct phrase is 'add up', meaning to calculate the total or sum. When you add up all the money someone owes, you're totaling the individual amounts. 'Add with', 'add to', and 'add over' are not correct for calculating totals in this context. 'Add up' can also mean 'to make sense' logically, but here it's about arithmetic.
