I cannot guarantee it is right but here you go
Here is your answer. 0.117658
P(x) = -0.4 + 100 - 300 + 500
C(x) = 600 + 300
R(x) = -0.4 + 700 - 600 + 500
P(x) = R(x) - C(x)
(-0.4 + 700 - 600 + 500) - (600 + 300)
= -0.4 + 100 - 300 + 500
This should be the answer.
See below in bold.
Round 492 to 500, then
estimate is 500/50 = 10.
