Problema Solution
A typical American baby weighs about 8 pounds at birth and gains about 1.5 pounds per month for the first year of life. What equation relates weight w in pounds to age a in months?
Answer provided by our tutors
the baby gains 1.5 pounds per month for the first year of life
in 'a' months it will gain 1.5*a pounds
we add the gained weight to the weight at birth to find the weight 'w' after 'a' months:
w = 8 + 1.5*a is the equation that relates weight 'w' in pounds to age 'a' in months.
