I need the answer right now

(C) 7.5 units.

Step-by-step explanation:

If an empty can weighs 3 units each, there are 12 cans. The cans by themselves would weigh 3 * 12 = 36 units. Since the total weights of the syrup in cans is 492 units, the 5 liters of syrup (without the cans) would weigh about 492 - 36 = 456 units.

12 of 5 liters of syrup, we can say there are 12 * 5 = 60 liters of syrup. So, to find the weight of 1 liter of syrup, we just need to do 456 / 60 = 7.6. That is approximately 7.5 units.

So, the weight of 1 liter of syrup alone (without a can) is most nearly (C) 7.5 units.

Hope this helps!
