Dilution of a solution of phenol with trichloroacetic acid

Hello,

I would like to solve the following problem:

I have a vial of trichloroacetic acid (TCA) at 30% (w/w) in aqueous solution.
I have a vial of phenol 88% (w/w) in aqueous solution.
What volume of phenol and volume of TCA should I mix to obtain 5 mL of solution where the phenol concentration would be 10% (w/w).
What would then be the concentration (w/w) in TCA.

Are there any formulas to solve this type of problem?
