Answer:
663
Step-by-step explanation:
the total number of students can be determined using this equation :
(total ratio of Chinese and Indian students / total ratio of students) x n = 468
total ratio of Chinese and Indian students = 4 + 8 = 12
total ratio of students 4 + 8 + 5 = 17
N = TOTAL NUMBER OF STUDENTS
12/17) x n = 468
multiply both sides of the equation by 17/12
n = 663
Eg is half the length of ac
Given:
x y
0 40
4 120
y = fixed amount + v(x)
y = 40 + v(0)
y = 40
y = 40 + v(x)
120 = 40 + v(4)
120 - 40 = v(4)
80 = v(4)
80/4 = v
20 = v
y = 40 + 20x
The fixed amount charged is 40.
The variable amount is 20 per day.
