From a bag of peanuts, phillip took 1/3, then joy took 1/4 of the remaining, brent took 1/2 of the remaining, and preston took 10. There were 71 peanuts remaining....how many were there to start?

let the number of peanuts be x
Phil took 1/3 of those, leaving 2x/3
Joy took 1/4 of those leaving (3/4)(2x/3) or x/2
Brent took 1/2 of those, leaving (1/2)(x/2) = x/4
Preston took 10 , finally giving us
x/4  10 = 71
x/4 = 81
x = 324
There were 324 peanuts 
when you divide 324 from how many kids the took peanuts you will get our answer which will come out to each child gets 81 peanuts from the bag.
