I need to create a formula for the following scenario ... any help would be
appreciated!

If value in cell is 3, then multiply another cell by .376, If 4, multiply by
..668, and so on. For instance:

A1 = 3
B1 = 4.5
Formula Cell C1 should return 1.69
OR
A1 = 4
B1 = 4.5
Formula Cell C1 should return 3.01


Can this be done?
