To find the amount of baking soda that Lisa should add to 9 lbs. of flour, we can use a proportion.

If 2 tsp of baking soda is added to 6 lbs. of flour, then the proportion is:

2 tsp / 6 lbs. = x tsp / 9 lbs.

Cross multiplying, we get:

2 * 9 = 6 * x

18 = 6x

Dividing both sides by 6, we find:

x = 3

So, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.

Therefore, the correct answer is 3 tsp.
