Julian has four times as many stickers as Flynn. Flynn has 8 more stickers than David. They have a total of 100 stickers.
- How many stickers does Julian have?
- How many stickers does David have?
(a)
Number of stickers that Flynn has = 1 u
Number of stickers that David has = 1 u - 8
Number of stickers that Julian has = 4 u
Total number of stickers
= 1 u + 1 u - 8 + 4 u
= 6 u - 8
6 u - 8 = 100
6 u = 100 + 8
6 u = 108
1 u = 108 ÷ 6 = 18
Number of stickers that Julian has
= 4 u
= 4 x 18
= 72
(b)
Number of stickers that David has
= 1 u - 8
= 18 - 8
= 10
Answer(s): (a) 72; (b) 10
