Since no indirect cost nor penaly cost information is offered, please consider the schedule and crash cost issues only,

Using Table of Crashing Decision, if the project's normal earliest completion time is to be reduced by two weeks, what is the minimum additional cost that will be incurred in achieving this two$-$week reduction?

less than or equal to $$1,000$

greater than $$1,000$ but less than or equal to $$1,500$

greater than $$1,500$ but less than or equal to $$2,000$

greater than $$2,000$
