Here are the data for a time$-$cost CPM scheduling model analysis. The time is in days and the costs include both direct and indirect costs.

Activity Immediate Predecessor Normal Time Crash Time Normal Cost Crash Cost

A None $32$ $ $200$ $ $400$

B A $43$ $ $300$ $ $600$

C A $11$ $ $300$ $ $300$

D B and C $32$ $ $500$ $ $550$

E D $21$ $ $500$ $ $900$

If you crash this project to reduce the total time by one day, what is the total time of the project and total cost?
