Step-by-step explanation:
The rocket better weigh more after it is fueled. So the weight must be 6.1*10^4 after fueling.
6.1 * 10^4 - 4.8*10^4
The easiest way to do this is to take it out of scientific notation.
61000 - 48000 = 13000 kg
If you insist on scientific notation, it is 6.1*10^4 - 4.8*10^4 = 1.3 * 10^4 which makes the answer C
