Please Check these
P(x)= .1(100)^2 +50(100)+300= 3,700,000
P(x)= .1(150)^2 +50(150) +300= 4,950,000
P(x)= .1(250)^2 +50(250) +300= 5,950,000
P(x)= .1(350)^2 +50(350) +300= 4,950,000
P(x)= .1(450)^2 +50(450) +300= 1,950,000

I don't know how you got these.
I will do the third one
P(250) = .1(250)^2 + 50(250) + 300
= .1(62500) + 125000 + 300
= 6250 + 12500+300
= 6550
