Gina Matheson owns and operates a successful florist shop in Bloomington, Indiana. Gina estimates that her variable costs amount to $0.25 per sales dollar (i.e., variable costs represent 25% of revenue) and that her fixed costs amount to $6,000 per month. Gina budgets for $16,000 in revenue per month.
This past May, Gina’s actual revenue was $21,000. Gina attributes part of the increase to seasonal holidays (Mother’s Day, Memorial Day) and part of it to higher prices. She figures that, taking advantage of a surge in demand, she was able to increase her prices by 5% this past month. Gina’s actual total costs for May were $12,100, which included $6,300 in fixed costs.
