Quizplus · Accepted Answer

The ratio of salt to water in the original solution is 5:14 or simplified to 5/14 pounds of salt per gallon of water. To find how many pounds of salt are needed for 28 gallons of water, we can set up a proportion:

5/14 = x/28

We can solve for x by cross multiplying:

14x = 5*28

x = 10

Therefore, 10 pounds of salt are needed for 28 gallons of water. So, the answer is B.
