Scenario: Your team is pulling together a grant proposal for your organization. Usually, a grant proposal budget includes the direct costs $($Personnel$,$ Equipment, Travel, Participants support, and Other Direct costs$)$ and indirect costs. Indirect costs are an additional budget expense to the direct costs of everything you plan to pay for with grant funds. They are typically calculated as a percentage of all or part of the direct costs. More commonly, institutions use modified total direct costs $($MTDC$),$ which is the sum of the direct costs less any budgeted amounts in the following categories: Equipment Capital expenditure Rental costs Patient care Tuition, scholarship, and fellowship Participant support Portion of each subaward in excess of $\backslash (\backslash$mathbf$\{\backslash$$ $25,000\}\backslash )$ Here is an example: Personnel $\backslash (=\backslash$$ $100,000\backslash )$ Travel $\backslash (=\backslash$$ $10,000\backslash )$ Participant Support $=$ Summer intern stipends: $\backslash$$$5,000$ per intern for $20$ interns Participant Support $\backslash (=\backslash )$ Summer interns' room and board: $\backslash$$$3,000$ per intern for $20$ interns Indirect cost rate $\backslash (=50\backslash )$ percent Part I. Please use the example to calculate the Indirect cost, then calculate the total budget for this proposal by summing up the direct and indirect costs. Please present your calculation processes, not just the total. Part II$.$ Using the budget items above, please create a brief budget narrative $($justification$)$ for each line item, explaining why each item is essential for grant implementation and how you come up with the estimates.
