Uniform Rates for Doing A JOB.


RT=J for relating rate, time, job quantity.
The rate of a group of agents all doing the same job is the sum of their individual rates, or for n agents which each work at r rate, the combined rate is nr.


{{{system(14r*3=220,nr*5=170)}}}
Solve for n.

That is a system of two equations in two unknown variables.  The first equation lets you solve for r.  The second equation lets you use r to find n, the number of gardeners.</PRE>
