I can see that it works when you write it down, but it's still not working
when I put it on the spreadsheet.

Numbers:
e4 = 4
f4 = 2

a4 = 6 = e4 + f4

i4 = (MIN(400,A4)*5+MAX(0,A4-400)*8) = (MIN(400,6)*5+MAX(0,-394)*8) = 30 +
0, so for a family of 6, it will be $30.

e5 = 2
f5 = 0

a5 = a4 + e5 + f5 = 8

i5 = (MIN(400,A5)*5+MAX(0,A5-400)*8) = (MIN(400,8)*5 + MAX(0,-392)*8) = 40 +
0. So for this family of two, according to the formula, it will cost them $40
instead of $10.

e6 = 392
f6 = 1

a6 = a5 + e6 + f6 = 401

i6 = (MIN(400,A6)*5+MAX(0,A6-400)*8) = (MIN(400,401)*5+MAX(0,1)*8) = 400*5 +
8 = 2008
should be $1968

Lets deal with numbers

a4 = 390
e5 = 9
f5 = 2

if I understand your question correctly

a5 = a4 + e5 + f5

Then somewhere (assume in {b5} you're multipling {a5} by 5 or 8 or a mixture
of the two)

in B5=Min(400,a5)*5+max(0,a5-400)*8

Min(400,a5)=Min(400,401)=400*5=2000
Max(0,401-400)=1*8 = 8

Therefore B5 = 2008 and b4 = 1950 = (390*5)

the cost for the family would be 2008-1950 = 58

If I knew more I could have a better answer - but this works.

Something still doesn't work, or I am having a braindead moment,

My cummulative column is A4, so initially A4 = E4 + F4
A5 = (A4 + E5 + F5) and so on.

My total column now multiplies A5*5. I need it to mutliply (E5 + F5)*5
unless one of the values makes the total greater than 400.

I am trying to write a formula charging the first 400 tickets $5 each. But as
soon as the 401st is sold, I need it to be $8.

Tickets are not being sold one at a time. This is for a family event, so it
could be 5 tickets at a time.

The current fomulas I have

=IF(A4<=400,(E4+F4)*5+G4*2,(E4+F4)*8+G4*2)

will charge $8 a ticket, if a family of 4 are tickets 398, 399, 400, and
401. I need the first three to be $5 each, and one ticket to be $8.


Where A4 is a cummulative column (A5's formula is =SUM(A4+E5+F5))
