The vice president of marketing and the director of human resources have developed a proposal whereby the company would compensate the sales force on a strictly commission basis. Given the increased incentive, they expect net sales to increase by 15%. As a result, they estimate that gross profit will increase by $59,856 and expenses by $86,728. Compute the expected new net income. Then, compute the revised profit margin and gross profit rate. (Ignore income tax effects.)

last year: gross profit:399156, net sale: 1308320, net income: 48692
