Final answer:
If the yield of broccoli is 55% and 10 pounds are needed for the recipe, you should order approximately 18.18 pounds, rounded up to 19 pounds to ensure you have enough after yield loss.
Step-by-step explanation:
To calculate how many pounds of broccoli should be ordered if the yield is 55% and 10 pounds are needed for the recipe, you use the formula:
Pounds needed = Amount needed for the recipe / Percent yield
In this case, the percent yield is 55%, or 0.55 as a decimal. Therefore, you need to divide the 10 pounds (the amount needed for the recipe) by 0.55 to find out how many pounds should be ordered:
pounds needed = 10 pounds / 0.55 = approximately 18.18 pounds
Since you cannot typically order fractional amounts of vegetables, it's best to round up to the nearest whole number. So, you would order 19 pounds of broccoli to ensure that you have at least 10 pounds after accounting for the 55% yield.
