Three guests checked in at ahotel and paid \$30 for their room. A while later, the deskclerk realized that the room should have cost only \$25, soshe gave the bellboy \$5 to return to the three guests. Thebellboy realized that \$5 couldn't be divided evenly amongthe three guests so he kept \$2 and gave \$1 to each of theguests. It seems that the three guests have now each spent\$9 for the room (that makes \$27) and the bell boy has \$2,for a total of \$29. Where is the missing dollar?
