Which store gives you the best deal?
metromarket
18cans of soda for $9
wal-town
10cana of soda for $7.50
shopstop
14cans of soda for $7.00

Metromarket sounds most logical to me because it is only $2.00 more than shopstop and you get 4 extra drinks. Out of shopstop and Wal-town you'd be better of at shopstop.

To find which store gives you the best deal we will find the unit rate for each store. Then we will check our work. Then at the end we will compare and see which stores is the cheapest. Lets do it;-

Metro market:-

18 ÷ 9 = 2
1 can = $2

CHECK OUR WORK:-

2 × 9 = 18
We were RIGHT!!

Wal-Town:-

10 ÷ 7.50 = 1.3333≈ 1.35
1 can ≈ $1.35.

Shop Stop

14 ÷ 7.00 = 2
1 can = $2

CHECK OUR WORK:-

2 × 7 = 14
We were RIGHT!!!

Price per can:-

Metro market = $2
Wal - Town ≈ $1.35
Shop Stop = $2

So the cheapest in this would be Wal-Town ($2).

Hope I helped ya!!
