For all real numbers b and c such that the product of c and 3 is b, which of the following expressions represents the sum of c and 3 in terms of b ?

Answer 1

Let c be a real number.
The product of c and 3 is b can be written as 3c = b.
Dividing both sides by 3, we get c = b/3.
The sum of c and 3 can be written as c + 3 = b/3 + 3 = (b + 9)/3.
Therefore, the given expression represents the sum of c and 3 in terms of b is (b + 9)/3. Answer: \boxed{\frac{b+9}{3}}.
