Waitress went to the cashier. Cashier said "Hey those guys received $5.00 discount."
Waitress realized she could not split $5.00 three ways equally so she pocketed $2.00.
She returned $1 to Person A, $1 to Person B, and $1 to Person C.
Person A initially paid $10.00; received $1.00 back; so Person A actually paid $9.00
Person B also actually paid $9.00
Person C is also $9.00
$9.00 times 3 = $27.00
$27.00 plus $2.00 the waitress pocketed = $29.00
Where in the heck is the missing $1.00?  |
The math is correct, your word problem is not:
10*3 = $30 original price of the tab
The guys paid $27
The tab cost $25
The waitress kept $2.
25+2 = 27 should be the real equation should be 27-2 = $25
So, there is not missing dollar. The additional sentence included at the end of the problem is incorrect. You would not add $2.00 to the $27.00 because it is already included. The amount the men spent, $25.00 for the bar tab plus the "stolen" $2.00 tip equals $27.00. It should be $27.00 spent plus $3.00 change equals $30.00.
