David and May began a partnership by investing $28,000 and $20,000 in cash, respectively, and during its first year the partnership earned a profit of $42,000. David spends twice as much time running the business as does his partner.

Assume instead that during its first year the partnership earned a $28,000 profit. What would be the share of each partner in the profit if the partners had agreed to share it by giving a $16,400 per year salary allowance to David and an $18,000 per year salary allowance to May, 10% interest on their beginning investments, and the remainder equally?

a. Davids share, $13,200; Mays share, $14,800.

b. Davids share, $14,000; Mays share, $14,000.

c. Davids share, $13,349; Mays share, $14,651.

d. Davids share, $13,600; Mays share, $14,400.

e. Davids share, $14,400; Mays share, $13,600.
