There is a sale for soft drinks, so four stores are competing with each other. which store offers the best buy? store a : 12 pack for $3.00 store b : 22 pack for $5: 50 store c : 18 pack for $4: 75 store d : 36 pack for $8: 00

store a single drink cost $3/12 =25c

store b single drink cost $5.50/ 22 = 25c

store c single drink cost $4.75/18 = 26c

store d single drink cost $8/36 = 22c

hence store d offers the best buy
