Two sizes of seaweed plants are growing in a cove. Due to changing water temperature,
the bigger seaweed plants are thriving while the smaller
plants are dying out. There
were
originally 25 large seaweed plants and 300
small seaweed plants. The large
seaweed is increasing in number by 2% a year and the
smaller plant is decreasing
by 6%
a year.
When
will
the
number of
each type of plant be equal?
