Question 1154838: The number of days that a given number of bushels of corn will last when feeding cattle varies inversely as the number of animals. If x bushels will feed 23 cows for 9 days, how long will the feed last for 9 cows? Answer by ikleyn(52775) (Show Source):
You have this proportion
= ,
where d is the number of days under the question.
The proportion says that the rate of consuming corn per day and per cattle is the same in both cases.
From the proportion, 23*9 = 9*d, which gives d = 23 days. ANSWER
Solved.
