Answer:
B. 60
Step-by-step explanation:
There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.
15% got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds
The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds
it means that the roots of the quadratic equation is real and distinct and that means that 40 is a positive value
