= a A person's intelligence quotient (IQ) is measured by the function I(m, a) = 100m where a is the person's actual age and m is his or her mental age. What is the IQ of a person whose actual age is 24 and whose mental age is 30? At what rate should his or her mental age be changing so that his or her IQ is increasing at a rate of ½ unit per year? Note: It is obvious that his or her actual age is increasing at a rate of 1 unit per year.
