chef has 50 pounds of strip zebra. the trim loss on the strip zebra is
40% and the cooking loss is 60% of the trimmed weight. how many
pounds of trimmed, cooked strip zebra will the chef have left to serve to
his customers?

12 pounds

Step-by-step explanation:

After trimming:

50 − 0.40 (50) = 0.60 (50) = 30

After cooking:

30 − 0.60 (30) = 0.40 (30) = 12

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
