[ 4 ] 4,500, 7,500, and 12,000, and appropriate work is shown, such as solving an equation or trial and error with at least three trials and appropriate checks.

[ 3 ] Appropriate work is shown, but one computational error is made.

or

[ 3 ] A correct equation is written and solved, resulting in an answer of 1,500, but the amounts given to the three workers are not computed.

[ 2 ] Appropriate work is shown, but two or more computational errors are made.

or

[ 2 ] The trial-and-error method is used to find the correct solutions, but only two trials and appropriate checks are shown.

or
