James needs to pay rent of $x a week.
He also needs to pay an additional 20% of rent for utilities, which is 0.2 * x = 0.2x.
The total cost for rent and utilities is x + 0.2x = 1.2x.
He has 2 employees per shift, and the store is open 16 hours a day for 5 days a week, which means each employee works 16 * 5 = 80 hours per week.
If he pays each employee $12.50 an hour, then the total cost for employee wages per week is 2 * $12.50 * 80 = $2000.
His weekly expenses to run the store is the sum of the cost for rent and utilities and the cost for employee wages: 1.2x + $2000.
We are given that the weekly expenses to run the store is $3440, so we can write: 1.2x + $2000 = $3440.
Subtracting $2000 from both sides, we get: 1.2x = $1440.
Dividing both sides by 1.2, we get: x = $1200.
The value of x is $1200.
#### 1200
The answer is: 1200
