A farmer bought a number of pigs for $280. However, 3 of them died before he could sell the rest at a profit of 6 per pig. His total profit was $120. How many pigs did he originally buy?

Answer 1

The $280 is a distraction!

p represents the number of pigs bought

p - 3 represents the number of pigs sold

6(p- 3) represents the profit on the sale

120 = 6(p - 3)

Can you solve for p and answer?
