Question

A farmer buys a horse for $60. He sells it to his neighbor for $70. Then he discovers he could have made a better deal. He borrows $10 from his wife, and buys the horse back for $80. He then sells it to another neighbor for $90. How much money did he make?

Answer 1

70$ (money he makes on the horse the first time) - 60$ (what he paid) = 10$ -10$ (the money he borrows) = 0$ - 80$ (he bought the horse back) = -80$ + 90$ = 10$ (positive)

Answer 2

He only made $10. Considering the horse was sold for $90.
