Hi there!
So we know that the two train together is a total of 192 tons and the difference of their weights is 120 tons...
Ok let think...
When we’re looking at the once place, you’ll see a two... this means that the two train both have a ending of 1 since 2 is split into 1...
That would be another clue..
Now let think again...
If it would be 151 and we subtract by 120.. we would get...
Well it ends with a 1 so it would be perfect but we have to see if 151 and 31 together adds up with the total of 192..
This means that train A could be 151 tons or 31 tons and train B can also be wither 151 tons or 31 tons...
If the US could make 14 stereos/hr or 7 cars/hr, this is a ratio of 2 stereos/1 car, or 1 stereo/0.5 cars. Therefore the US opportunity cost of producing 1 stereo is 0.5 car of half a car.
If China (or Japan? given the question in #2) makes 15 stereos/hr or 5 cars/hr, this is a ratio of 3 stereos/1 car, or 1 stereo/0.33 cars.
63 divided by 12 is <span>5.25</span>
