You can but 9 cans of green beans at the village market for $4.12.you can buy 7 of the same green beans at dams clubs for 4.22 witch place is the better buy

The easy way to do this is divide each of them by their respected price...

4.12 ÷ 7 = .47 per can Cheapest

4.22 ÷ 9 = .59 per can Most

I encourage you to look at it in this formula too...

9V = 4.22

7D = 4.12

then divide like we already did to find village price a can and dams price a can.
