Suppose a small business has sales of $10,000 this month, with future sales expected to grow by $1,900 each month. Costs consist of a fixed component, which is $4,000 per month, and a variable component, which is 35 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 7 months from now?
