the number of students in a school doubles every month. if there are 14000 students in the school, how many students were there in the school four months ago?
14000 * (1/2)^4 = 14000/16 = 875
1 month ago = 7000
2 months ago = 3500
3 months ago = 1750
4 months ago = 875
Oh, boy, the school's students are multiplying like rabbits! Let's do some funny math to figure this out. If the number of students doubles every month, then we can reverse engineer this situation. If there are 14,000 students now, then four months ago, there must have been half that amount since the number doubled each month. So, get ready for the grand reveal... *drumroll*... four months ago, there were 7,000 students clowning around in that school!
To find out how many students were in the school four months ago, we can work backwards from the given information.
Let's say x represents the number of students in the school four months ago.
Since the number of students doubles every month, we can set up the following equation:
x * 2 * 2 * 2 * 2 = 14000
Simplifying this equation, we get:
x * 16 = 14000
Dividing both sides of the equation by 16, we find:
x = 14000 / 16
x = 875
Therefore, there were 875 students in the school four months ago.
To determine the number of students in the school four months ago, we need to work backward from the given information.
Let's start with the current number of students, which is 14,000. We know that the number of students doubles every month. Therefore, to find the number of students four months ago, we need to halve the current number of students four times.
Let's go step by step:
1. Current number of students: 14,000
2. One month ago: Halve the current number (14,000 / 2) to get 7,000 students.
3. Two months ago: Halve the number of students one month ago (7,000 / 2) to get 3,500 students.
4. Three months ago: Halve the number of students two months ago (3,500 / 2) to get 1,750 students.
5. Four months ago: Halve the number of students three months ago (1,750 / 2) to get 875 students.
Therefore, there were 875 students in the school four months ago.
