Formula HELP

[Sara Bolinger]

Need help setting up a formula for Excel.

C4<15 then C4*2

C4>15 BUT <23 then C4*1.65

C4>23 then C4*1.4

NEED THESE (3) MULTIPLES TO DEVELOP (1) ANSWER

C4 IS 19.79      so in cell E4 the answer is 32.65

[#2]

That could be

=C4*LOOKUP(C4,{0,15,23},{2,1.65,1.4})

[#3]

Thank you!!  Did exactly what I needed done.
