Step-by-step explanation:
Company A:
Buy 300 shares at $1.45 per share.
Sell 300 shares at $1.65 per share.
Profit: ($1.65 - $1.45) * 300 = $60
Company B:
Buy 200 shares at $1.20 per share.
Sell 200 shares at $1.10 per share.
Loss: ($1.20 - $1.10) * 200 = $20
Net profit:
$40 - $20 = $20
12x3+27x2+23x+10/ 4x+5
3x2 + 3x + 2
V=πr^2h/3=π·3^2·11.5/3≈108.38495 or 108.40 rounded
