Sagot :
Answer:
44.98% ≈ 45%
Step-by-step explanation:
You want the yield percentage when 28 heads of cauliflower weighing 2 lbs each result in 25 lbs 3 oz after cleaning and trimming.
Yield
The yield is the ratio of cleaned cauliflower to the original weight:
[tex]\text{yield}=\dfrac{25\text{ lb }3\text{ oz}}{28\cdot(2\text{ lb})}=\dfrac{25.1875\text{ lb}}{56\text{ lb}}\approx0.449777\approx\boxed{44.98\%}[/tex]

Additional comment
There are 16 ounces in a pound, so 3 oz is 3/16 lb. The fraction is converted to a percentage by multiplying it by 100%.
Here, 1 oz represents about 0.11% of the original weight, so we feel there is some justification for maintaining 2 decimal places in the percentage figure. For the purpose of estimating a necessary purchase of cauliflower, it is likely that using a yield factor of 45% would provide sufficient accuracy.
