This should be the correct answer
Answer:
Step-by-step explanation:
24,000 inspected.....50 were defective
50/24,000 reduces to 1/480 <===
3/4 = x / 340....3 to 4 students = x to 340 students
cross multiply
(4)(x) = (3)(340)
4x = 1020
x = 1020/4
x = 255 <==
or this way.....
3 out of 4 students.....3/4 = 75%
so 75% of 340 = 0.75(340) = 255 <=
They need to be number C plus 3-2:7
