Final answer:
There are 22.2 pounds of water in a 30 lb bag of potatoes, calculated by multiplying the weight of the bag (30 lb) by the percentage of water (74%) as a decimal (0.74).
Step-by-step explanation:
The question asks us to calculate the amount of water by weight in a bag of potatoes that weighs 30 lb, given that 74% of a potato is water. To find the answer, multiply the total weight of the bag by the percentage of water.
First, convert the percentage to a decimal: 74% = 0.74.
Now, multiply the total weight of the bag by this decimal:
30 lb × 0.74 = 22.2 lb
So, there are 22.2 pounds of water in the bag of potatoes.
