Answer 1

Answer: Grocery Mart: $1.75 per 1lb

Baldwin Hills Market: $1.67 per 1lb

Explanation:

For the first one what you wanna do is divide 5 by 2.85 which then you will get a decimal that is infinite so then you round to the nearest tenth

A: $1.75 per 1lb

Grocery Mart

For the second one you wanna do the same thing and divide 7 by 4.20 and then the answer would be an infinite number of 6 so then you round to the nearest tenth again.

A: $1.67 per 1lb

Baldwin Hills Market

The best deal is Baldwin Hills Market since its cheaper per pound

The difference between Baldwin hills market and grocery mart is 8 since 1.75 - 1.67 is 8.

Answer 2

Grocery Mart has a better price for potatoes

Grocery Mart: $0.57 per lb
Baldwin Hills Market: $0.60 per lb

To get the answer you set it up as fractions
5/2.85=1/x (5lb over $2.85) (1 lb over x). X is our missing number. A quick way to get the answer is do 2.85 times 1 = 2.85 then divide that number by 5 and you get x=0.57
Do the same with 7/4.20, 4.2 times 1 equals 4.2 then divide by 7 and you get x=0.6

I hope this explains everything :)
