Woah! Those are some big numbers! Anyways heres my answer: I used the old school way of fuigreing this out but using the pencil and paper I fuigred out 546463+54543 is equal to 601006 and if you were to multiply this by 64 (it took a LONG time for me and quite a few mess ups) its 38464384. Though I gave you the answer I'm just wondering if you could use a calculator because it would be a whole lot easier if you were able to do so.
If you divide 100 by 4 which equals 25 that would be 25mins for one ugly sweater If you times by 2 that equals 50 If 6=4+2 then you add 100 and 50 together which makes 150.
