Frisk will be paid P2,500 for cleaning up the lawn after the one-month selling period. Brisk, Whisk and Frisk decide that net income, if any will be allocated first by the P2,500 payment to Frisk and then by a 40% commission on individual sales. The balance will be distributed 75% to Brisk and 25% to Whisk. They agree that a cash box will complicate the matters and that all purchases and sales transactions will be out-of-pocket and the responsibility of the individual.
