Question

For children between the ages of 5 and 13 years, the Ehrenberg equation

ln W = ln 2.4 + 1.84h

gives the relationship between the weight W (in kilograms) and the height h (in meters) of a child. Use differentials to estimate the change in the weight of a child who grows from 1.4 m to 1.5 m. (Round your answer to two decimal places.)
