swat32

Answer:

Ian sold 7 rolls of wrapping paper.

Step-by-step explanation:

Let E be the number of rolls of wrapping paper sold by Evan and I be the number of rolls of wrapping papers sold by Ian.

We have been given that Evan sold twice as many rolls of wrapping paper as Ian. We can represent this information in an equation as:

E=2I...(1)

We are also told that Evan sold 14 rolls.

We can represent this information in an equation as:

E=14...(2)

To find the number of rolls of wrapping paper sold by Ian we will equate our both equation as:

2I=14

Let us divide both sides of our equation by 2.

\frac{2I}{2}=\frac{14}{2}

I=7

Therefore, Ian sold 7 rolls of wrapping paper.
