5. Mary plans to sell two different software products: X and Y. Assume the budgeted sales mix (3 units of X sold for every 2 units of Y sold) will not change. A total of 100 units (60 units from product X and 40 units from product Y) has been sold, with unit price of $200 for product X and unit price of $100 for product Y. Variable costs are $120 for each unit of product X and $70 for each unit of product Y. Assuming $4,500 as the total fixed costs of the total sold products, the total operating income equals (in $) (2 points) less than or equal to 1,250 Greater than 1,450 greater than 1,250 but less than or equal 1,350 greater than 1,350 but less than or equal 1,450
