This problem can be used as a Problem of the Week.

    1. Susan should be paid $7.50. Lynne should be paid $2.50.
    2. Drawings should reflect that Susan raked 3/4 of the lawn and Lynne raked 1/4 of the lawn. Possible response:



    1. Bob should be paid $5.00.
    2. Each boy should be paid $2.00 for raking the last two-thirds.
    3. Bob should be paid $7.00; $5 + $2 = $7
    4. There are three $5 in $15.00 so 1/3 of $15.00 is $5.00; that leaves $10 for the last 2/3. 5 boys raked the rest so they divide the $10 evenly.
