Profit is the difference between the selling and the cost prices
The number of pigs he originally buys is 15.
Let the number of pigs be x.
When 6 pigs died, the remaining pigs are:
[tex]\mathbf{x - 6}[/tex]
The total profit is calculated as:
[tex]\mathbf{Profit = 5\times(x - 6)}[/tex]
[tex]\mathbf{Profit = 5x - 30}[/tex]
The total profit is 47.
So, we have:
[tex]\mathbf{5x - 30 = 47}[/tex]
Add 30 to both sides
[tex]\mathbf{5x = 77}[/tex]
Divide both sides by 5
[tex]\mathbf{x = 15.4}[/tex]
[tex]\mathbf{x = 15}[/tex] ---- approximated
Hence, the number of pigs he originally buys is 15.
