A = -16 b = 0 c = 541
Use the quadratic formula which is
x = [-b +- sq root (b^2 -4*a*c)] / 2*a
x = [-0 +-sq root (0 -4*-16*541)] / 2 * -16
x = + - sq root (0 -4*-16*541) / -32
x = + - sq root (34,624) / -32
x = + - 186.075 / -32
x1 = 186.075 / -32 =

That would be 35 + 0.20*35 = $42
Answer:
5/8
Step-by-step explanation:
would be reduces all the way by 3
Since the multiplicative inverse of a fraction p/q is the fraction that swaps its numerator and denominator, i.e. q/p, we have that the inverse of 2/3 is 3/2.
So, if we multiply both sides of the equation by 3/2, we have

3/2 and 2/3 are multiplicative inverse of each other, and by definition this means that they give 1 when multiplied:

On the right hand side, we have

And so the solution is
