Question 928830: Please help me to solve this Rational expression and Equations word problem:
Farming. The length of time a given number of bushels of corn will last when feeding cattle varies inversely as the number of bushels will feed 25 cows for ten days, how long will the feed last for 10 cows?
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
we have the following equation
t = k * 1 / b(25) = k / b(25), where k is constant of proportionality
10 = k / b(25)
k = 250
t = 250 / b(10) = 25
25 days for 10 cows
