# The Missing Dollar Riddle

Kevin explores the math and mystery behind a classic riddle that just… doesn’t make sense. Three friends go out to lunch and split a \$30 bill evenly. Each pays ten bucks. Then the waitress realizes the bill should’ve been only \$25.

She gives the busboy a \$5 refund, but he can’t figure out how to evenly divide five dollars three ways. The customers don’t even know they’ve been overcharged, so he just takes a \$2 tip for himself and hands the three customers one dollar each.

If the customers only paid \$9 each for lunch and the busboy pocketed \$2, where is the missing dollar?!?
