Teacher Steve

I'm trying to write a formula with the following data using Excel '03:

If a student is tardy once, then it costs him $100. Twice, then it costs
him $200 and the previous $100 and $200 need to be added to show that it cost
him $300 total. If a student is tardy three times, then it costs him $300,
plus the previous $100 and $200, for a grand total of $600. I would like
this formula to go up to ten tardies and not use Visual Basic. or tables.

Thank you!

Steve
 
I'm the teacher, not the student!! I have an Excel SS that I use to
calculate student grades and such. This formula would help me because
tardies are a part of student grades. Please help.
 
If you put the number of tardies in A1, you can use this formula to get your
total money!

=(A1*(A1+1)/2)*100

If you can't go over 5500, you can use this variation:
=MIN(5500,(A1*(A1+1)/2)*100)

(10 tardies results in $5500)
 
Thanks so much, Dave, that was so simple!!
