Okay. So Martin will definitely have the 8 tickets he won. In addition, he has $20 to buy more tickets. Let's say that each ticket that he buys costs x dollars. If they are $5 each, he could buy 4 tickets because $20/$5 = 4. Plus, he would still have the 8 he won initially.
Therefore, F(x) = 20/x + 8 would be the correct answer.
