If total incurred cost in a production process are $30000 and number of output units are 5000 units, then units cost will be

$16
$60
$6
$26

The correct answer is C. $6.

The units cost is the total cost of production divided by the number of output units. In this case, the total cost is $30000 and the number of output units is 5000, so the units cost is $30000 / 5000 = $6.

Option A is incorrect because $16 is the total cost divided by 2500, which is the number of output units if the units cost were $6.

Option B is incorrect because $60 is the total cost divided by 500, which is the number of output units if the units cost were $12.

Option D is incorrect because $26 is the total cost divided by 2000, which is the number of output units if the units cost were $15.
