(a)
Total number of stickers received = 5 u
5 u = 75
1 u = 75 ÷ 5 = 15
Total number of stickers that Albert, Luke and Charlie received
= 75 - 15
= 60
Total number of stickers that Albert, Luke and Charlie received
= 1 p + 5 p
= 6 p
1 p = 60 ÷ 6 = 10
Number of stickers that Albert received
= 1 p
= 10
(b)
Number of more stickers that David received more than Luke
= 1 u - 1 p
= 15 - 10
= 5
Answer(s): (a) 10; (b) 5
