A distribution depot uses one reusable transit crate for 40 deliveries. Alternatively, it could use a new cardboard carton for each delivery. The crate is returned and cleaned after every delivery.
The table shows the mass of carbon dioxide released when each container is manufactured.
| Process | Mass of carbon dioxide released in kg |
|---|---|
| Manufacturing one reusable transit crate | 9.6 |
| Manufacturing one cardboard carton | 0.40 |
Over the 40 deliveries, manufacturing the crate and returning and cleaning it releases 3.2 kg less carbon dioxide in total than manufacturing the 40 cardboard cartons.
What is the mass of carbon dioxide released by returning and cleaning the crate after one delivery?
0.24 kg
0.16 kg
0.08 kg
0.32 kg
