Fractional Saturation of Hemoglobin

[catie1981]

Homework Statement

Calculate fractional saturation (YO2) for hemoglobin at venous O2 pressure (30 torr). Assume that p50 for hemoglobin is 26 torr, Hill constant is 3.

Homework Equations

YO2/1-YO2=(pO2/p50)^n

The Attempt at a Solution

(30/26)^3=1.54=(YO2/1-YO2)= 1.54 - 1.54YO2= YO2

This is pathetic. I am so mathematically retarded it hurts. How to solve for YO2...I can't seem to get it alone...why do they always play hard to get...grrr. Thanks for any help.
