Edwards and Bell market a single line of home computers, dubbed the XL$-98.$ The master budget for the coming year contained the following items: sales revenue, $$400,000$; variable costs, $$250,000$; fixed costs, $$100,000.$ Actual results for the year were as follows: sales revenue, $$350,000$; variable costs, $$225,000$; fixed costs, $$95,000.$ The flexible$-$budget operating income for the year was $$35,000.$
