I don’t get it why do you add 150 twice
first time 150 is added because question was that
and second time because we need to find 250% of 150
But the scientists has a population of 150 flies not 300
ohhh Now I get it sorry to disturb you
my bad
Bye
you can only calculate the 250% of 150 by multiplying it.It is the only method
