this is going to sound dumb..

but how do i use these numbers: 62000, 12200, 7500, 4600, 2200 and 5000. to make them equal 45900.

oh and ps, im not sure if youre meant to use the 5000 or not, coz im supposed to use those numbers to calculate WIP.

Please help me because I've been doing this problem all week but i can't figure out how they got 45900 with those numbers

thank you
