Let's focus on the given equation. The C represents the cost, while the x must be the number of tacos, which is what we're solving for. Since we're given the boundary that C must be 300, then the solution would be:
300 = x² - 40x + 610
x² - 40x + 310 = 0
Apply the quadratic formula where a = 1, b = -40 and c = 310. The roots of x are:
x = 29.49≈30
x = 10.51≈11
<em>Thus, she needs to sell either 30 or 11 tacos.</em>
300 = x² - 40x + 610
x² - 40x + 310 = 0

Answer:
Step-by-step explanation:
Comparing it with quadratic equation , we get:
a = 1 . b = 4 and c = 5
So,
Discriminant =
D = (4)²-4(1)(5)
D = 16 - 20
D = -4
Hence,
Discriminant = -4
