You can put this solution on YOUR website!
you want to hire 30 people in 10 days.
your passing rate per day is 30%.
you want to know how many people you have to interview per day to get your 30 people in 10 days.
let x = number of people you interview per day.
your formula would be:
.3*x*10 = 30
solve for x to get:
x = 30/(.3*10) which results in:
x = 10 per day.
let's see if that works.
you interview 10 people per day.
you hire 3 of them each day.
in 10 days you have hired 30 people.
it works.
you need to interview 10 people per day.
