$130.35
Step-by-step explanation:
Tomas needs to spend less than or equal to $1000.
Let's say the price he spends each day is x.
The plane ticket is a one time cost, so it doesn't need a variable.
So the price Tomas would be spending is:
348.25 + 5.5x
Remember, this has to be less than or equal to $1000.
So our inequality becomes:
5.5x + 348.25 ≤ 1000
Subtracting 348.25 from both sides, we get
5.5x ≤ 651.75
Dividing both sides by 5.5, we get
x ≤ 130.35
Therefore, Tomas can spend up to $130.35 every day in order to stay under the cost of $1000.
I hope this helps!
