Checking for each option

Option A: A(w) = -w^2+200w

Substitute w = 10 and check if we'd get 900 as the answer
A(10) = -(10)^2+200(10) = -100+2000 = 1900

Option B: A(w) = -w^2+100w
Substitute w = 10 and check if we'd get 900 as the answer
A(10)=-(10)^2+100(10)=-100+1000=900

Option C: A(w)=w^2+40w
Substitute  w = 10 and check if we'd get 900 as the answer
A(10) = 10^2+40(10)=100+400=500

Option D: A(w) = w^2+90w
Substitue w = 10 and check if we'd get 900 as the answer
A(10)=10^2+90(10) = 100+900=1000

Answer: Option B
