HELP ME PWEASEE Fifteen grams of chemical A is used to produce 3 grams of chemical B. Write an
equation for the amount of chemical B, measured in grams of chemical A, b = f(a), as a function of the amount of chemical, 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.

    ...(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 .

b is the correct answer
