I need conditional formatting based on percentage variance of another value

I am trying to highlight a cell in column B if it is +/- 5% of the value in column C. So if column C is 100 and in column B i enter 94 or less or enter 106 or more it turns red. Thanks for any help.

Try
=OR(B2<C2*0.95,B2>C2*1.05)

Works great, thanks!
