the number of plants used to fill a row of given length in a garden varies inversely as the distance between the plants. if 75 plants r used to fill the row wen planted 20cm apart, how many plants are used to fill the row when planted 15cm apart?
---------------------------
p = k/d
Find "k":
75 = k/20
k = 1500
---------------
EQUATION:
p = 1500/d
---------------
Find # of plants if distance = 15 cm.
p = 1500/15
p = 100 plants
