To solve this problem, we can use a ratio.
The ratio of baking soda to flour is 2 tsp:6 lbs.
To find the amount of baking soda for 9 lbs of flour, we can set up a proportion:
2 tsp/6 lbs = x tsp/9 lbs
Cross multiplying, we get:
6x tsp = 2 tsp * 9 lbs
Simplifying, we have:
6x tsp = 18 tsp * lbs
Dividing both sides by 6 tsp, we find:
x = 18 tsp
Therefore, Lisa should add 18 tsp of baking soda to 9 lbs of flour, which is option A.
