If the cooking loss for a hamburger patty is 20%, how many pounds of meat must be purchased to serve 40 guests a 6 oz. patty?

Question

A. 18 lbs. 12 oz.

B. 15 lbs. 4 oz.

C. 17 lbs. 13 oz.

D. 16 lbs. 8 oz.

Answer 1

To serve 40*6 oz. means to serve 240 oz.

 

If this is 80% of the original (that is, there has been a 20% loss), then the original must be 240/.8 = 300 oz.

 

300 oz is 18 lbs 12 oz   [since 1 lb = 16 oz]
