Answer:
1.2 trains for $25.
Step-by-step explanation:
For 50 dollars, you could get 2.4 trains with the $25 dollar option.
For 90 dollars (an extra 40 dollars!) you only get 0.2 more trains.
If you add another $25 to the current $50 on the other option, you get 3.6 trains.
So, 1.2 trains for $25 must be the better option as you can get an extra 1 train for 15 dollars less!
Hope this helps!
Also, who buys 0.2 or 0.6 of a train? -_-
Answer:
When an electron moves to a higher energy level, it absorbs energy. Since the electron in the lower energy level has lower energy, so to move into a higher energy level it would require more energy hence it would absorb energy to equalize the higher energy
