Melanie is buying soft drink cans for the work fridge. In the shopping catalogue, she sees a 10 can
pack for $6.00 and a 24 can pack for $15.96. Which is the cheapest way for Melanie to buy the soft
drink? Show all working

Answer :

If you buy the 10-pack you pay 60 cents per can ($6.00 / 10 cans = .60/can). If you buy the 24-pack, you pay more than 66 cents per can ($15.96 / 24 cans = .665/can). So it is cheaper to buy the 10-pack (60 cents vs. 66 cents for each can)
