Question: Hi Fliers is considering making and selling custom kites in two sizes. The small kites would be priced at $9 and the large kites would be $24. The variable cost per unit is $5 and $11, respectively. Jill, the owner, feels that she can sell 2,600 of the small kites and 1,700 of the large kites each year. The fixed costs would only be $2,100 a year and the tax rate is 34 percent. What is the annual operating cash flow if the annual depreciation expense is $900?
