Suppose a small business has sales of $11,000 this month, with future sales expected to grow by $1,300 each month. Costs consist of a fixed component, which is $5,500 per month, and a variable component, which is 30 percent of sales. Design a spreadsheet to compute the gross profit (revenue less fixed and variable costs) per month over a nine month period. What is the gross profit in a single month 8 months from now?
