Answer:

$300

Step-by-step explanation:

10% converted into a decimal is 0.10.

To find 10% of 3,000, you would multiply them.

3,000 times 0.10 is 300.

Therefore, Nora spends $300 a month on clothes.

Consider the diagram of the problem.

Let the vertex be on the y axis, exactly, at the point (0, 40)

Another point of this parabola is (200, 100), as can be checked from the figure.

The vertex form of the equation of a parabola is :

$y=a(x-h)^{2}+k$ , where (h, k) is the vertex of the parabola,

replacing (h, k) with (0, 40), we have:

$y=ax^{2}+40$

to find a, we substitute (x, y) with (200, 100):

$100=a200^{2}+40$

40,000a=60

a=60/40,000=3/(2,000)

So, the equation of the parabola is $y= \frac{3}{2000} x^{2}+40$
