a. G division increased sales by $85,000 per year, how much would the company's net income change? Cost behaviors remained same

b. Assume the R division increased sales by $100,000, the G division sales remained the same and no change in fixed costs.
1. Calculate the net income for each division and the total for company
2. Calculate the segment margin ratios before and after these changes
