If you buy 2 packs of 500 mL milk, it will cost $2.50. If you buy them individually, they will cost $1.30 each. How much is your total savings from buying ten sets of 2 packs of 500 mL milk?
Step-by-step reasoning:
1
The price per 500 mL milk from the 2 packs is $2.

50 / 2 = $1.

25.

This means that for each pack of 500 mL milk, you can save $1.

30 - $1.

25 = $0.

05.

Ten sets of 2 packs mean 10 x 2 = 20 packs of 500 mL of milk.

So, your total savings will be $0.

05 x 20 = $1.

.

The final answer: 1
