Answer: The man has 10$.

Step-by-step explanation:

We start with the number 60. He sells the goat for 70 dollars, and makes a 10 dollar profit. Then, he buys it for 80$, leaving him with 0. But then he sells it for 90$, making another profit of 10$.

The amount of money a man has at the end of the given transactions is required.

The amount of money the man has at the end is [tex]\$20[/tex]

Cost price and selling price:

The total amount of money spent buying the goat is [tex]60+80=\$140[/tex]

The total amount of money received when selling the goat is [tex]70+90=\$160[/tex]

The total amount of money the man has at the end would be the difference of the selling price and cost price.

[tex]160-140=\$20[/tex]
