Answer:
2x+12y
Step-by-step explanation:
1 is rounded out
23 + 24 + 25 = 72
23 is the answer
45.864, because 57.33 divided by 100 is 0.5733 that multiplied by 80 is 45.864
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>
