hi, i'm not sure if you still need the answer but i'll still try to help.
so to work out this question, you must find out how many fans will be packed in 8 hours.
you know:
32 fans / hr
to find this:
= 32 x 8 (multiply by 8 because you have an 8 hour shift)
= 256
then:
= 1483 - 256 (original - 8h shift fans)
= 1227
therefore, 1227 fans will be left in the warehouse at the end of your 8 hour shift.
