One store sells milk for $3.00 per gallon. A second store sells milk for $0.80 per quart.If you need two gallons, which store should you buy from?

4 quarts in a gallon= $3.20

1st store: $3.00 per gallon
2nd store: $3.20 per gallon.

1st store is cheaper, so 1st store

To compare the prices of milk at both stores, we need to find the price per gallon for the second store since it is given in quarts.

Given that the second store sells milk for $0.80 per quart, we need to convert this price to per gallon. There are 4 quarts in a gallon, so to get the price per gallon, we need to multiply the price per quart by 4.

Price per gallon at the second store = $0.80/quart * 4 quarts = $3.20 per gallon.

Now, we can compare the prices at both stores. The first store sells milk for $3.00 per gallon, while the second store sells milk for $3.20 per gallon.

Therefore, for two gallons of milk, it is cheaper to buy from the first store, where the price per gallon is $3.00.
