Question 877387
Let m = rate of work for 1 man and b = rate of work for 1 boy.  Call one piece of work, 1 job.


The rate of any two agents working simultaneously are simply combined as addition.  The "while" is the comparison operation for equality.


The description is numerically transcribed as:
{{{(2m+3b)*10=1=(3m+2b)*8}}}, which is really TWO equations.
