(a)
The number of staplers remains unchanged.
Number of notebooks that Victoria gave away or sold
= 4 u - 3 u
= 1 u
1 u = 34 + 39 = 73
Number of notebooks that Victoria had at first
= 4 u
= 4 x 73
= 292
(b)
Total number of notebooks and staplers that Victoria had at first
= 1 u + 4 u
= 5 u
= 5 x 73
= 365
Answer(s): (a) 292; (b) 365
