Cognitive demand: medium. Typical question shape: Dilated figure; find scale factor or missing side.

Tatiana is organizing a school fundraiser. She decides to sell cookies and brownies. If she makes a total of 120 cookies and brownies, and the ratio of cookies to brownies is 3:2, how many cookies does she make?

  1. 72
  2. 48
  3. 60
  4. 30

Why: To find the number of cookies, first, we add the parts of the ratio 3 (cookies) + 2 (brownies) = 5 parts total. Then, we determine the value of one part by dividing the total number of treats by the total parts: 120 / 5 = 24. Since cookies are 3 parts, we calculate 3 * 24 = 72. Therefore, Tatiana makes 72 cookies.
