How Much Tip

Of the 960 people in a theater, 17% tipped 5 cents to the usher, 50% of the remaining 83% tipped 10 cents, and the rest tipped nothing. How much did the usher get?

Puzzle Answer


Answer:
If half of the 83% tip the usher 10 cents and the other half doesn't, it is the same as if all 83% had tipped him 5 cents, which is the same amount as what the remaining 17% tipped. The usher received 4,800 cents, or more simply, 48 dollars.
