Celia wants to spend no more than $100 a week on food, so her total spending on food for the month is 4 * $100 = $400.
For rent, she plans to spend x.
She has $30 set aside for video streaming services and $50 planned for one month of cell phone usage, so her total spending on these two items is $30 + $50 = $80.
After she adds up all of her spending for the month, her total spending is $400 + x + $80 = $480 + x.
She wants to set aside 10% of her total spending to put into savings, so the amount she puts into savings is 10/100 * ($480 + x) = 0.1 * ($480 + x) = 0.1 * $480 + 0.1 * x = $48 + 0.1 * x.
We are given that the amount she puts into savings is $198, so we can write: $48 + 0.1 * x = $198.
Subtracting $48 from both sides, we get: 0.1 * x = $150.
Dividing both sides by 0.1, we get: x = $1500.
The value of x is $1500.
#### 1500
The answer is: 1500
