The cost C of running a school is directly proportional to the number of students N, if 20 students cost #10,000, How many students can #1,000,000 cover?
The cost C of running a school is directly proportional to the number of students N, if 20 students cost #10,000, How many students can #1,000,000 cover?
Answer Details
To answer this question, we need to use the formula for direct proportion: C = k * N, where C is the cost, N is the number of students, and k is the proportionality constant.
Since we know that 20 students cost #10,000, we can find the value of k by substituting the known values into the formula:
10,000 = k * 20
Solving for k:
k = 10,000 / 20 = 500
Now that we have the value of k, we can use it to find the number of students that #1,000,000 would cover:
C = k * N
1,000,000 = 500 * N
N = 1,000,000 / 500 = 2000
So, #1,000,000 would cover 2000 students.
