Answer:
Afternoon class has more students.
Step-by-step explanation:
Let m be the number of students in the morning class and n be the number of students in the afternoon class.
The average score for the students in the morning class was 80, then the sum of their scores is 
The average score for the students in the afternoon class was 86, then the sum of their scores is 
The sum of the scores of both classes is
and the average score is
The average (arithmetic mean) score for the two classes combined was 84, then
This means n is greater, so afternoon class has more students.
2 would most like be doubled and be 4 I think...
She would have to score atleast a 74 on the test for her average to be 78
Answer:
So roughly c x c = b/100
5 x 5 x 100 = $2500
Step-by-step explanation:
Lets say c = 5 and b = 1
= 5c =100c/5c x b
= 20c x b
We can also show
= 20c x b =5c
c = 20c/5c x b = 5c
1/20 x 5c = 5c
b=1
One example is 20% = 0.20 x 500 = 100c
= 7.12c = 7c
1= 100%
100 x 71.042 = 710.42 weekly pay. emergency tax 142 = 568
100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107
710-107 = 603 a week
4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29
It's C. move all terms to the left side and set equal to zero. then set each factor equal to zero.
