which process??

 A major construction project has included in the project budget the cost of the construction loans taken out to finance the work, and this will be accounted for on a monthly basis. The project manager will factor in these cost estimates into the project during which process?

Activity Duration Estimates will affect cost estimates on any project where the project budget includes an allowance for the cost of financing, including interest charges, and where resources are applied per unit of time for the duration of the schedule activity

I vote Determine Budget process since these cost estimates have already been created and will serve as inputs into the budget.
