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
$A(10)=10^2+90(10) = 100+900=1000$
