The brain mass of a fetus can be estimated using the total mass of the fetus by the function b=0.22m0.87 where m is the mass of the fetus (in grams) and b is the brain mass (in grams). Suppose the brain mass of a 20g fetus is changing at a rate of 0.28g per day. Use this to estimate the rate of change of the total mass of the fetus, dm/dt.
