Answer 2

Answer:

We should buy at Store 1

Step-by-step explanation:

To compare both stores ,  we have to get the price of 2 gallons of milk in each of them.  

Store 1 sells 1 gallon for $3.00

So,  2 gallons will be

Price = $3.00 x 2 = $6.00

Store 2 sells milk for $0.80 per quart.

Each gallon has 4 quarts,  so 2 gallons will be 8 quart

Price = $0.80 x 8 = $6.40

Store 2 is more expensive than Store 1 ,  so we should buy at Store 1
