tablespoons of pepper to make 16
liters of gravy. If Martha's recipe is for 1 liter of gravy, how much pepper will she need to make double the recipe?

D 12 tablespoons of pepper
D. 12 tablespoons of pepper
Assuming the 23 tbl of pepper would be a typo and should read
2/3 tbl .....
16 litres need 2/3 tbl of pepper
1 litre needs (2/3)/16 or 1/24 tbl of pepper
so if she doubles her recipe, she will need 2/24 or 1/12 tbl of pepper
you really need to learn how to type fractions, dude ...
To solve this problem, we need to determine the proportion of pepper used in Martha's original recipe and use that to calculate the amount needed for double the recipe.
First, we need to find out how much pepper Martha used per liter of gravy in her original recipe. We do this by dividing the total amount of pepper used (23 tablespoons) by the total amount of gravy (16 liters):
Pepper per liter = 23 tablespoons / 16 liters ≈ 1.4375 tablespoons per liter
Next, we need to determine how much pepper Martha would need to make double the recipe. Since she used 1.4375 tablespoons per liter in her original recipe, we can simply double that amount to find the total amount of pepper needed for double the recipe:
Pepper for double the recipe = 1.4375 tablespoons per liter × 2 liters = 2.875 tablespoons
Therefore, Martha would need approximately 2.875 tablespoons of pepper to make double the recipe.
The correct answer is:
A) 2 tablespoons of pepper
