Answer :
Firstly chef will lose 55% from 80 pounds, then he will lose 60% of what he had left, so we need to do two calculations:
55% from 80 pounds =
= 55% * 80 =
= 55/100 * 80 =
= 11/20 * 80 =
= 880/20 =
= 44
So after the trimming chef will have 44 pounds of strip loin. After cooking he will lose 60% of the trimmed weight, so:
60% from 44 pounds =
= 60% * 44 =
= 60/100 * 44 =
= 6/10 * 44 =
= 3/5 * 44 =
= 132/5 =
= 26 2/5 =
= 26 4/10 =
= 26.4
Answer: After trimming and cooking, chef will have 26.4 pounds of strip loin.
55% from 80 pounds =
= 55% * 80 =
= 55/100 * 80 =
= 11/20 * 80 =
= 880/20 =
= 44
So after the trimming chef will have 44 pounds of strip loin. After cooking he will lose 60% of the trimmed weight, so:
60% from 44 pounds =
= 60% * 44 =
= 60/100 * 44 =
= 6/10 * 44 =
= 3/5 * 44 =
= 132/5 =
= 26 2/5 =
= 26 4/10 =
= 26.4
Answer: After trimming and cooking, chef will have 26.4 pounds of strip loin.
