Substitute a=50 and h=160 into the given equation:


.041(160)-.018(50)-2.69 = 6.56 - .9 - 2.69 = 2.97 liters.

lung+capacity=0.041h-0.018a-2.69
height=h=160
age=a=50
Substitute in the equation at the top the values given for a and h
lung+capacity=0.041%2A160-0.018%2A50-2.69=6.56-0.9-2.69=2.97
The lung capacity of that woman is estimated at 2.97 liters.
