The song was conceived when Guetta played the instrumental version during one of his DJ sets in summer 2008; American recording artist Kelly Rowland, who fell in love with the track, convinced Guetta to allow her to take it so that she could write and record vocals for it.
Divide the total fixed costs by the quantity of units produced in order to get the average fixed cost. For example, if your fixed cost amount totals $10,000 and you produce 1000 units, then your AFC will be $10.
Thus, the cost per unit is not constant. For example, ABC Company has total variable costs of $50,000 and total fixed costs of $30,000 in May, which it incurred while producing 10,000 widgets. The cost per unit is: ($30,000 Fixed costs + $50,000 variable costs) / 10,000 units = $8 cost per unit.
