Answer:
5,040 cars
Step-by-step explanation:
Each truck weighs 7.2 tons, and there are already 480 trucks loaded. This means that the cargo ship is currently carrying 3,456 tons.:
480 x 7.2 = 3,456
The limit is 21,600 tons, so 21,600 - 3,456 = 18,144.
Divide the remaining capacity by how much a car weighs:
18,144 / 3.6 = 5,040
