Answer:
.
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.
...(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).
Substitute in (1).
Therefore, the required function is .
