The grocery mart offers the best deal on potato’s and price per pound is $0.03 less than Baldwin Hills market.

Explanation

At grocery mart, a 5 pounds bag of potatoes cost $2.85

So, the unit price of potatoes per pound at grocery mart $=\frac{\$ 2.85}{5}=\$ 0.57$

Now at Baldwin Hills market, 7 pounds bag of potatoes cost $4.20

So, the unit price of potatoes per pound at Baldwin Hills market $=\frac{\$ 4.20}{7}=\$ 0.60$

As $\$0.57$ , that means the unit price of the potatoes per pound at grocery mart is less than the Baldwin Hills market.

So, the grocery mart offers the best deal on potato’s.

The price of the potatoes per pound at grocery mart is $(\$0.60-\$0.57)=\$0.03$ less than the price at Baldwin Hills market.
