Question 321532: I am not sure how to add the height in this problem. Is it written right? I cannot figure out the answer
The polynomial 0.14h-0.018a-2.69 can be used to estimate the lung capacity, in liters, of a female with height h, in centimeters, and age a, in years. Find the lung capacity of a 40-year-old woman who is 160 centimeters tall.

Since "the lung capacity of a 40-year-old woman who is 160 centimeters tall", we know that h=160 and a=40. Plug these values in to get 0.14%28160%29-0.018%2840%29-2.69=22.4-0.72-2.69=18.99 so this means that the lung capacity is about 18.99 liters.
