Using multiple ranges in one fuction

[apar93]

I need help putting together an IF(AND( formula that allows for multiple ranges.
1ST 2ND 3-5 6-10
3 X 5 ..... $100 $60 $35 $30

FOR 3-5 I tried: IF(AND(A76="3X5",B76>=3,B76<=5),((B76-2)*35)+160) which worked! But when I tried the second range 6-10 it said invalid. Help please!!!
