Bob,

Since his total profit was $42 and his profit per pig was $6, the number of pigs sold was $42÷ ($6 per pig) = 7 pigs sold.

We are also told that 6 pigs died, so the total number of pigs bought was 7 + 6 =13

I also noticed that you posted a number of problems. You might want to consider finding a tutor near you to help.
