What is the cost of the units transferred out? (Use rounded cost per equivalent unit.)

Units completed and transferred out:
Units transferred to the next department	12,600	12,600
Cost per equivalent unit	$13.50	$89.60
Cost of units transferred out	$170,100	$1,128,930	$1,299,030

I typed 1299030, it says incorrect. I dont know what it means by round cost per equivalent unit? what would be the cost of units transferred out if it rounded cost per equivalent unit is used?
