Question

Collen is touring an automobile. The tour guide tells her that they use 938 kg of aluminum to make 7 cars. All of the cars are the same so they use the same amount of aluminum for each car if they have only used 100 kg of aluminum on the car they are building right now how much more aluminum do they need to finish the car?

Answer 1

34kg

Explanation:

To first find out how much is used in each car divide 938 by 7, which equals 134.

Next you need to subtract how much has already been used (100kg) from that answer, leaving 34kg needed to finish the car.
