Answer:
D). Diego is correct because the price of one can of soda multiplied by the number of sodas needed will give you the total cost of the soda.
Step-by-step explanation:
Since every person is expected to drink one can of soda:
Let the price of each can of soda = p
and the total number of people present at the picnic = n
∵ Total price = p(the price of each soda can) * n(number of people)
Thus, Diego correctly asserts that if he multiplies the 'unit price for a can of soda by the number of people attending the picnic', he would be able to deduce the total cost of soda. Hence, Max is incorrect and option D is the correct answer.
