Are you sure you got the point system correct, you have 2 values for 1 (0 and
5) and no value for 10, so I am going to presume you meant:
1=0, 2=5, 3=10 and 4=15
If that is correct, then this formula will give you the answer (60)
=(SUMIF(A1:I1,">1",A1:I1)-COUNTIF(A1:I1,">1"))*5
That formula simply ignores 1s completely; it gets the total of all values
greater than 1 and effectively subtracts 1 from each of them and multiplies
the result by 5.
so
4-1=3 and 3*5 = 15
1 ignored
4-1=3 and 3*5 = 15
3-1=2 and 2*5 = 10
2-1=1 and 1*5 = 5
1 ignored
1 ignored
2-1=1 and 1*5 = 5
3-1=2 and 2*5 = 10
and finally 15+15+10+5+5+10 = 60
