Answer:

He is not correct because the answer is 20.5%.

Step-by-step explanation:

Multiply 5400lb by 2 and you get 10,800 and thats how much he filled up. Then half of 60,000lb is 30,000lb and half of 100% is 50%. So 30,000 is equal to 50%. Then half of 30,000lb is 15,000lb and half of 50% is 25%. So 15,000 is equal to 25%. So next subtract 4,200lb from 15,000lb and you get 10,800lb. So then subtract 4.5% from 25% and you get 20.5%. So therefore, 10,800lb is equal to 20.5%.
