Question 1000608
This is the second sentence part of the description:
T is time to do the painting
P is how many painters
k is proportionality constant or variation constant;

{{{T=k/P}}}
  

The first sentence means  {{{18=k/1}}}
{{{k=18*1*(hours)(painters)}}}


{{{highlight(T=18/P)}}}.


What if P=4?
{{{T=18/4}}}
{{{T=9/2}}}
{{{highlight(T=4&1/2)}}}
