(a)
The number of files remains unchanged.
Number of staplers that Anna gave away or sold
= 5 u - 4 u
= 1 u
1 u = 32 + 24 = 56
Number of staplers that Anna had at first
= 5 u
= 5 x 56
= 280
(b)
Total number of staplers and files that Anna had at first
= 1 u + 5 u
= 6 u
= 6 x 56
= 336
Answer(s): (a) 280; (b) 336
