(a)
Before
Number of pens that Sam had = 1 u + 268
Number of pens that Flynn had = 1 u
After
Number of pens that Sam had = 1 u + 268 + 59 = 4 u
Number of pens that Flynn had = 1 u
1 u + 268 + 59 = 4u
1 u + 327 = 4 u
4 u - 1 u = 327
3 u = 327
1 u = 327 ÷ 3 = 109
(a)
Number of pens that Flynn had
= 1 u
= 109
(b)
Number of pens that Sam and Flynn had in the end
= 4 u + 1 u
= 5 u
= 5 x 109
= 545
Answer(s): (a) 109; (b) 545
