Respuesta :
0,5, and 8 are the 3 that are correct. You cannot have negative bags of course. Also it cannot be 10 because the balloon cannot hold that much weight.
Answer:
8
Step-by-step explanation:
You subtract 300 from 140 to get 160 because the pilot adds the weight in already. Once you get 160 divides it by 20 to get 8. Each bag weighs 20 pounds, every bag you add will decrease the total the air balloon can carry, so anything 8 and less is good. (4), (5), and (0) should be your answer.
