Answer:

First we must learn to dissect a question.

Explanation:

Part 1

We can list our facts first:

  • Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
  • She needs 13 dozen cookies

She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons

[tex]6.5 \times 1.5 = 9.75 \: teaspoons[/tex]

Part 2

She needs 9.75 teaspoons and 3 teaspoons make a tablespoon

So..

[tex]9.75 \div 3 = 3 r0.75= 3tbsp \: and \: 0.75tsp[/tex]
