To calculate the variance, subtract your actual fixed overhead cost from your standard overhead cost. If the actual cost is higher than the fixed cost, the cost variance is unfavorable. For example, your standard fixed overhead cost is $3 per unit.
The major role of hemoglobin is to carry oxygen from the lungs to the tissues and return carbon dioxide (CO2) from the tissue to the lungs.
