Find all real numbers c and d such that the product of d and 3 is c, which of the following expressions represent the sum of d and 3 in terms of c?

- c + 3
- 3c + 3
- 3(c + 3)
- (c + 3)/3
- c/3 + 3

**Answer:**

We are given that the product of d and 3 is c.

3d=c

Now we must isolate d so that we can add its value to 3.

3d=c, or

d = c/3

Let us now add this value to 3. We get

c/3 + 3

**Our final answer is 5**

**, which is c/3 + 3.**
