To find out how much baking soda Lisa should add to 9 lbs. of flour, we can set up a proportion.

Let's calculate the ratio of baking soda to flour in the first scenario: 2 tsp baking soda / 6 lbs. flour.

Now, we can use this ratio to find out how much baking soda Lisa should add to 9 lbs. of flour:

2 tsp baking soda / 6 lbs. flour = x tsp baking soda / 9 lbs. flour.

To solve for x, we can cross multiply and divide:

(2 tsp baking soda) * (9 lbs. flour) = (6 lbs. flour) * (x tsp baking soda).

18 tsp baking soda = 6x tsp baking soda.

To isolate x, divide both sides of the equation by 6:

18 tsp baking soda / 6 = 6x tsp baking soda / 6.

3 tsp baking soda = x tsp baking soda.

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

To solve this problem, we need to find the ratio of baking soda to flour and then apply that ratio to the new amount of flour.

We know that Lisa added 2 tsp of baking soda to 6 lbs. of flour. So, the ratio of baking soda to flour is 2 tsp : 6 lbs.

To find the amount of baking soda needed for 9 lbs. of flour, we can set up a proportion.

Let's set up the proportion using the ratio we found:

2 tsp / 6 lbs = x tsp / 9 lbs

Now, we can solve for x:

(2 tsp * 9 lbs) / (6 lbs) = x tsp

(18 tsp) / (6 lbs) = x tsp

3 tsp = x tsp

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

So, the correct answer is: 3 tsp
