He pays 7 percent to health insurance.
7 percent of 490 is 34.30. (490 x 0.07)
ALSO: question 1 answer is actually $298.90
This is the standard form equation 
What is the ellipse?
The equation for an ellipse is typically written as x² a² + y² b² = 1. x² a² + y² b² = 1. An ellipse with its origin at the center is defined by this equation. The ellipse is stretched further in both the horizontal and vertical directions if a > b, a > b, and if b > a, b > a, respectively.
The standard form of the equation of an ellipse with center (h, k)and major axis parallel to the x-axis is:

where,
a > b
the length of the major axis is 2a
the coordinates of the vertices are (h±a,k)
the length of the minor axis is 2b
the coordinates of the co-vertices are (h,k±b)
the coordinates of the foci are (h±c,k),
where c² = a² − b².
so,

Hence, this is the standard form equation

It is the second answer:
8x²/y -2 is a solution which is equivalent to (8x²-2y)/2. Proof:
Reduce 8x²/y -2 to the same denominator:
8x²/y - 2y/y = (8x² - 2y)/y
