To determine which combination of items Liam can sell, we need to check both the total number of items and the total revenue generated from each option.

  1. 50 cookies and 30 muffins:

    • Total items = 50 + 30 = 80 (valid)
    • Total revenue = (50 * 3) + (30 * 5) = 150 + 150 = $300 (valid)
  2. 30 cookies and 25 muffins:

    • Total items = 30 + 25 = 55 (valid)
    • Total revenue = (30 * 3) + (25 * 5) = 90 + 125 = $215 (invalid)
  3. 40 cookies and 20 muffins:

    • Total items = 40 + 20 = 60 (valid)
    • Total revenue = (40 * 3) + (20 * 5) = 120 + 100 = $220 (invalid)
  4. 25 cookies and 30 muffins:

    • Total items = 25 + 30 = 55 (valid)
    • Total revenue = (25 * 3) + (30 * 5) = 75 + 150 = $225 (invalid)

From the options, the only valid combination that meets the goal of raising at least $300 while keeping the total items sold to a maximum of 80 is:

50 cookies and 30 muffins.
