(a)
The number of pens remains unchanged.
Number of staplers that Jane gave away or sold
= 5 u - 4 u
= 1 u
1 u = 33 + 49 = 82
Number of staplers that Jane had at first
= 5 u
= 5 x 82
= 410
(b)
Total number of staplers and pens that Jane had at first
= 1 u + 5 u
= 6 u
= 6 x 82
= 492
Answer(s): (a) 410; (b) 492
