(a)
Before
Number of stickers that Paul had = 1 u + 209
Number of stickers that Carl had = 1 u
After
Number of stickers that Paul had = 1 u + 209 + 49 = 3 u
Number of stickers that Carl had = 1 u
1 u + 209 + 49 = 3u
1 u + 258 = 3 u
3 u - 1 u = 258
2 u = 258
1 u = 258 ÷ 2 = 129
(a)
Number of stickers that Carl had
= 1 u
= 129
(b)
Number of stickers that Paul and Carl had in the end
= 3 u + 1 u
= 4 u
= 4 x 129
= 516
Answer(s): (a) 129; (b) 516
