option B) 3 pounds of beef is needed to make 6 times the recipe.
Step-by-step explanation:
step 1 :
Mitch used 14 pounds of beef = 34 liters of beef strogonoff
'x' pounds of beef = 1 liter of beef strogonoff
step 2 :
Rate = No. of pounds / No. of liters
(14 pounds / 34 liters) = (x pounds / 1 liter)
x = 14/34
x = 0.412
1 liter of beef strogonoff = 0.412 pounds of beef
step 3 :
To make 6 times the recipe = 6
0.412
= 2.5 pounds of beef ( approximately 3 pounds)
