please help with making the total project cost . step by step. using the below to crash the project.

Use the following table to crash the project Compute the total direct cost for each project duration. If the indirect costs for each project duration are $450 (22 time units). $400 (21 time units). $350 (20 time units), $300 (19 time units. $250 (18 time units), and $200 (17 time units), compute the total project cost for each duration. Then answer the questions. Hints: You may not need to use all the given indirect costs. This means your normal project duration may be shorter than 21 time units and/or the crash point may be longer than 17 time units.
