travel causes it to lose 1 kg of cargo. There are 300 kgs of cargo available at the base
camp. Find the maximum amount of cargo (in kg) that the ship can transfer to the
station? Assume that the spaceship can store the cargo at any intermediate point along
the way and that stored cargo is not depleted by the asteroids. 641+852+973=2456 is not correct. what is the largest digit that can changed to make the correct addition
