Answer :
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Number of ounces steaks = 4.5 oz
Number of guests = 180
Percentage of waste = 25%
Number of ounces of fresh steak is given by
[tex]4.5\times 180\\\\=810\ oz[/tex]
Let the number of ounces of raw steak be x.
According to question,
[tex]\dfrac{100-25}{100}\times x=810\\\\\dfrac{75}{100}\times x=810\\\\0.75\times x=810\\\\x=\dfrac{810}{0.75}\\\\x=1080\ oz[/tex]
As we need in pounds, and we know that
1 pound = 16 ounces
So, Number of pounds of raw steak that Chef could order is given by
[tex]\dfrac{1080}{16}=67.5\ lbs[/tex]
Hence, Option 'c' is correct.
