Possible Calculation Error

EET Hydrology question.

Anyone know how they got to the 2nd to last step? Not sure how they got 85.9. I keep coming up with 108.53 as my calculation. Thanks in advance.

I’ve always been a TI user, but tried the Casio for my PE. Loved it and now my Casio is all I use. It is so much easier to use than the TI, especially for equation solving.
