Answer:
x+10
Explanation:
So they did a bet, and placed 5 cents each. George lost the bet that gives Joyce 5 points plus 5 more that make 10.
After the bet George has: x cents
Before the bet George had: x + 5 cents
Before the bet Joyce had also x + 5 cents
Since Joyce won 5 cents, after the bet she has x + 5 + 5 = x + 10 cents.
