Hard to do when you don't define your variables ...
but
break even means "they are equal"
-4/5 x^2 + 10x = 2x + 15
The solution to that is indeed 5/2 and 15/2 , but we don't know what x is
Assuming Profit = Revenue - Cost
= -4/5x^2+10x - (2x+15) , sub in x = 100
= -4/5 (10000) + 1000 - 200 - 15
= -7215 ??????
define what x is !
