If Statement with Choices

Thanks in advance for the help.

A1 = "Flute"
B1 = "Glue" or "Tape"
C1 = 10
D1 = Answer


I need help with an if statement.

C1 = 10, add 1/8 if A1 = Flute, if not add 1/4

At the same time I need to know, AND/OR?

if B1 = Glue or Tape, then add 3/16 to the overall number

Tricky part, if A1 does not equal Flute it should be 1/4 added to C1, I would like if B1 = Glue or Tape then add on 5/16 because Flute is not there. Below is better explanation.

A1: Flute
B1: Glue
C1: 10 + 1/8 + 3/16

A1:
B1: Glue
C1: 10 + 1/4 + 5/16

A1: Flute
B1:
C1: 10 + 1/8

A1: blank or another word
B1: blank or another word
C1: 10 + 1/4


Thanks for the help.
