Consequently, When Love Takes Over was shelved until Guetta rediscovered the song when compiling his fourth studio album, One Love. The finished song with Rowland's vocals and Guetta's production was premiered in March 2009 at the Ultra Music Festival in Miami.
A related concept is marginal cost. Average fixed cost is the total fixed cost per unit of output incurred when a firm engages in short-run production. It can be found in two ways. Because average fixed cost is total fixed cost per unit of output, it can be found by dividing total fixed cost by the quantity of output.
In this example, fixed costs are $50,000. The first chart shows that fixed costs remain $50,000 at all production levels from 100 units to 1,000 units. The second chart shows that the fixed cost per unit decreases as production increases. Hence, when 100 units are manufactured, the fixed cost per unit is $500 ($50,000  100).
