(a)
Before
Number of stickers that Justin had = 1 u + 241
Number of stickers that Andy had = 1 u
After
Number of stickers that Justin had = 1 u + 241 + 47 = 5 u
Number of stickers that Andy had = 1 u
1 u + 241 + 47 = 5u
1 u + 288 = 5 u
5 u - 1 u = 288
4 u = 288
1 u = 288 ÷ 4 = 72
(a)
Number of stickers that Andy had
= 1 u
= 72
(b)
Number of stickers that Justin and Andy had in the end
= 5 u + 1 u
= 6 u
= 6 x 72
= 432
Answer(s): (a) 72; (b) 432
