You run a lab that performs a single blood test that calculates an overall 'wellness' assessment, providing a report that gives information on a number of key short and long term health indicators.
Before the start of the year you prepared a budget projecting sales, costs and profit on a monthly basis. This budget assumed monthly sales of 1700 units at a price of $33.50 each. You projected that variable costs would be $13 a unit in labor and $15 in materials and supplies per test.
At the end of January, you looked at your actual results for the month and prepared a flexible budget.
Here are the 3 budgets side by side.
                   Static                 Flexible                   Actual
Revenues                            $56,950             $47,737.50             $49,875
Variable Cost                     $47,600               $39,900                $41,500
Fixed Cost                         $6,000                  $6,000                 $6,250
Profit                                  $3,350                 $1,837.50            $2,125
What is contributing to the change in profit? In other words, explain where the profit differentials are coming from.   Feel free to attach any calculations to support your answer.
