Step-by-step explanation:

Quarts of vinegar 3: Cups of Baking soda :4 |

According to the recipe, exactly how many cups of baking soda need to be mixed with 9 1/2 quarts of white vinegar

From the above recipe

3 quarts of vinegar = 4 cups of baking soda

9 1/2 quarts of vinegar = x

Cross Multiply

3 × x = 4 × 9 1/2

3x = 4 × 19/2

x = 4 × 19/2 ÷ 3

x = 4 × 19/2 × 1/3

x = 12.666666667 cups of baking soda or 12 2/3 cups of baking soda

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

ou would have 12 of each
