Answer:
at least 9 students in each cohort.
Step-by-step explanation:
Given that :
In a class, there are 25 students and each of them is either a sophomore, a freshman or a junior. We have to determine the number students in the same cohort.
Let us suppose there are equal number of students in each of the cohort.
Now let us assume that the number of the students in each cohort be 8, i.e. each as a freshman, a junior or a sophomore. Therefore, the total number in the all the cohorts will be 24 students only.
Thus, we can say that there are at least freshman, at least sophomore or at least junior in each of the cohort.
3x+4=52
-4 -4
3x=48
divide by 3 on both sides
x=16
Answer: $5780
Step-by-step explanation:
Mrs. Jackson gave sum of money to her son and daughter in the ratio 8:9 and her daughter received $3,060. To get the total amount given to the children goes thus:
Son = 8
Daughter= 9
Total = 8+9 = 17
Let the total amount given to the children be y. Since the daughter's share is $3060.
= 9/17 × y = 3060
= 9y/17 = 3060
9y = 3060 × 17
9y = 52020
y = 52020/9
y = 5780
Mrs Jackson gave out $5780
