D'(p) = -8p + 160
<span>-8p + 160 = 0 </span>
<span>-8p = -160 </span>
<span>p = 20 </span>
<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>
<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>
I think this is right, i tried.

Answer:
Let's simplify step-by-step.
3a − 2 ( 8 + 4a )
Distribute:
= 3a + ( −2 ) ( 8 ) + ( −2 ) ( 4a )
= 3a + −16 + −8a
Combine Like Terms:
= 3a + −16 + −8a
= ( 3a + −8a ) + ( −16 )
Answer:
= −5a − 16
