(a)
Before
Number of buttons that Flynn had = 1 u + 207
Number of buttons that Albert had = 1 u
After
Number of buttons that Flynn had = 1 u + 207 + 41 = 3 u
Number of buttons that Albert had = 1 u
1 u + 207 + 41 = 3u
1 u + 248 = 3 u
3 u - 1 u = 248
2 u = 248
1 u = 248 ÷ 2 = 124
(a)
Number of buttons that Albert had
= 1 u
= 124
(b)
Number of buttons that Flynn and Albert had in the end
= 3 u + 1 u
= 4 u
= 4 x 124
= 496
Answer(s): (a) 124; (b) 496
