Terry Willard and Jasmine Hill decide to form a partnership. Willard will contribute $300,000 to the partnership, while Hill will contribute only $30,000. However, Hill will be responsible for running the day-to-day operations of the partnership, which are anticipated to require about 45 hours per week. In contrast, Willard will only work five hours per week for the partnership. The two partners are attempting to determine a formula for dividing partnership net income. Willard believes the partners should divide income in the ratio of 7:3, favoring Willard, since Willard provides the majority of the capital. Hill believes the income should be divided 7:3, favoring Hill, since Hill provides the majority of effort in running the partnership business. How would you advise the partners in developing a method for dividing income?
