The value of x is -2√2 or 2√2.

**Step-by-step explanation:**

Given that y is inversely proportion to x², y ∝ 1/x². So the formula will be y = k/x² where k is the constant. In order, to find the value of k, you have to substitute the values of x and y into the formula :

Next, you have to substitute the y value into the equation to find x :

Multiply the cost of the meal by 0.15 ( 15% as a decimal).

Not enough information is false because you can infer that it is 45 degrees by looking at it.

Hope that helps!
