Question

Susan and John are buying cold drinks for a neighborhood picnic. Each person is expected to drink one can of soda. Susan says that if you multiply the unit price for a can of soda by the number of people attending the picnic, you will be able to determine the total cost of the soda. John says that if you divide the cost of a 12 pack of soda by the number of sodas, you will determine the total cost of the sodas. Who is right, and why?

Answer 1

John's method will find you the price of each individual can of soda.Susan's method will find you the total cost of the soda. total number of cost = the number of things x the cost of each thing 

Answer 2

Susan is right. Susan's method helps you find the cost because through her method, you can find the total cost based on the number of people attending. John's method will help determine how many soda packs are needed.

Hope this helps you! :D
