<PRE><B>Question 879316</B>
In terms of just words:
( number of weeds on lawn ) = ( rate of change ) * ( number of days since spring started )
+ ( a fixed number of weeds )
------------------------------------
( number of weeds on lawn ) - ( a fixed number of weeds ) =  ( rate of change ) * ( number of days since spring started )
------------------------------------
( rate of change ) = ( Number of weeds on lawn + fixed number of weeds ) / ( number of days since spring started )
------------------------------------
You could say the rate is in units of: ( weeds ) / ( days )
