One piece is 28 inches long and the other is 14. If you divide 42 by 3 you get 14 and 14 times 2 is 28. That leaves the last piece at 14.
So since the constant is the same we could divide them. If you know when you divide powers of 10 you subtract so it would be 5.34/5.34 which is 1 and 10^5- 10^-2. 5 - (-2). Which is 10^7 so it would be 1*10^7
$1337 * 0.04 * 14 = <span>748.72
answer is </span><span>B)
$748.72 </span>
Loss: 3 (spaceships) * 20 (points per spaceship)
