Last year population = S
loss every year = 4000
so this year you will have S-4000 species

WOW i am reall good at math and i cant figure this out…. S is for last year so S- 4000 but that still dont say how many is living today B/C you dont even have a number that was there last yr or a number of species that is alive now????? all i can think is maybe they just want to see how you solve it S-4000 is all i got sorry

the num of species left = (S-4000)
