(a)
Before
Number of beads that Dylan had = 1 u + 261
Number of beads that Perry had = 1 u
After
Number of beads that Dylan had = 1 u + 261 + 60 = 4 u
Number of beads that Perry had = 1 u
1 u + 261 + 60 = 4u
1 u + 321 = 4 u
4 u - 1 u = 321
3 u = 321
1 u = 321 ÷ 3 = 107
(a)
Number of beads that Perry had
= 1 u
= 107
(b)
Number of beads that Dylan and Perry had in the end
= 4 u + 1 u
= 5 u
= 5 x 107
= 535
Answer(s): (a) 107; (b) 535
