One of Santa's elves can make one toy each minute. Every 2 minutes 1 toy falls apart. Every 5 minutes Santa takes 3 toys. If two elves are working in a room that contains 30 toys, than how many toys will there be after an hour, assuming that Santa has just left and that the elves work for the full hour?

Santa takes away  12 * 3   =  36 toys in the  hour

 

Number of toys that the  elves can make in one  hour =  2 (60)   =120

 

Number of toys  that  fall apart = 60 /2   = 30

 

 

So......number of toys  starting  out  -  ones that Santa takes  - number that fall apart  +  number that elves make  =

 

30   - 36  - 30  +  120  =  

 

120  - 36   = 

 

84 toys  after one hour
