Answer:
7200 people
Step-by-step explanation:
Let's say x amount of people tried out.
After round 1: 1/2 x are left.
After round 2: 1/3 (1/2 x) are left
After round 3: 1/4 (1/3(1/2 x))) are left
Each time we multiply by the fraction that are left. By the end we will have
1/6(1/5(1/4(1/3(1/2 x))))
So to find it multiply the denominator out:
![\frac{1}{6}*\frac{1}{5}*\frac{1}{4}*\frac{1}{3}*\frac{1}{2} x\\\\\\\frac{1}{6*5*4*3*2}x\\\\\frac{1}{720}x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%2A%5Cfrac%7B1%7D%7B5%7D%2A%5Cfrac%7B1%7D%7B4%7D%2A%5Cfrac%7B1%7D%7B3%7D%2A%5Cfrac%7B1%7D%7B2%7D%20x%5C%5C%5C%5C%5C%5C%5Cfrac%7B1%7D%7B6%2A5%2A4%2A3%2A2%7Dx%5C%5C%5C%5C%5Cfrac%7B1%7D%7B720%7Dx)
To find x, we set it equal to 10.
![\frac{1}{720}x =10\\x= 10*720\\x=7200](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B720%7Dx%20%20%3D10%5C%5Cx%3D%2010%2A720%5C%5Cx%3D7200)
