Stella [2.4K]

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

<em><u>Explanation</u></em>

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

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

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

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

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

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.
