What set of coordinates satisfies the equations 3x- 2y = 15 and 4x - y =20?

$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!
