سؤال 49

Pack A has 6 notebooks for 8.40 dollars. Pack B has 10 notebooks for 13.50 dollars. Which is the better buy if the notebooks are identical?

  1. Pack A, because its total price is lower.
  2. Pack A, because it has fewer notebooks.
  3. Pack B, because each notebook costs less.پاسخ درست
  4. Pack B, because its total price is higher.

توضیح

Pack A costs 1.40 dollars per notebook, while Pack B costs 1.35 dollars per notebook, so Pack B gives the lower unit price. Choosing Pack A only because 8.40 dollars is the lower total price ignores that it contains fewer notebooks.
