Answer:

b=\dfrac{1}{5}a.

Step-by-step explanation:

We need to write an  equation for the amount of chemical B as a function of the amount of chemical A.

b=f(a)

b\propto a

b=ka     ...(1)

where, k is constant of proportionality.

It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.

Substitute a=15 and b=3 in (1).

3=k(15)

k=\dfrac{3}{15}=\dfrac{1}{5}

Substitute k=\dfrac{1}{5} in (1).

b=\dfrac{1}{5}a

Therefore, the required function is b=\dfrac{1}{5}a.
