To find the amount of baking soda Lisa should add to 9 lbs. of flour, we can set up a proportion:
2 tsp baking soda/6 lbs. of flour = x tsp baking soda/9 lbs. of flour
Cross-multiplying, we get:
6*x = 2*9
Simplifying:
6x = 18
Dividing both sides by 6:
x = 3
So Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
Therefore, the answer is C. 3 tsp.
To find the answer, we can first set up a ratio that relates the amount of baking soda to the amount of flour. Since Lisa adds 2 tsp of baking soda to 6 lbs of flour, the ratio of baking soda to flour is 2 tsp:6 lbs.
Now, we need to find the amount of baking soda to add to 9 lbs of flour. We can use this ratio to set up a proportion:
2 tsp / 6 lbs = x tsp / 9 lbs
To solve for x (the unknown amount of baking soda to add), we can cross-multiply:
6 lbs * x tsp = 2 tsp * 9 lbs
6x = 18
Next, divide both sides of the equation by 6 to isolate x:
x = 18 / 6
x = 3
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs of flour.
So, the correct answer is C. 3 tsp.
To determine the amount of baking soda Lisa should add to 9 lbs. of flour, we can set up a proportion based on the ratio of baking soda to flour.
The ratio of baking soda to flour is 2 tsp per 6 lbs. of flour.
We can set up the proportion as follows:
2 tsp / 6 lbs. = x tsp / 9 lbs.
To solve for x, cross-multiply and then divide:
(2 tsp)(9 lbs.) = (6 lbs.)(x tsp)
18 tsp = 6x
Dividing both sides by 6:
18 tsp / 6 = 6x / 6
3 tsp = x
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
So the correct answer is C. 3 tsp.
