Mr. Valdez has 500 sows, and 50 sows are farrowing at a time. The sow average 8.8 pigs per litter with an average weight of 2.1 pounds. The pig were weaned at 6 weeks and sold at 8 weeks weighing an average of 50 pounds per pig. The pigs were sold for $110 per hundredweight. a. What fractional part of the sows is farrowing at the same time? b. What is the average daily gain per pig? c. How many pigs were raised if each sow has two litters per year?

Solution for question a:

Given that there are 500 sows and 50 sows are farrowing at a time.

Therefore, the fractional part of the sows farrowing at the same time is,

$$\begin{gathered} =\frac{50}{500} \\ =\frac{1}{10} \end{gathered}$$

Hence, ${\frac{1}{10}}^{th}$ of the sows are farrowing at the same time.
