Dylan and Perry have 16 balls altogether. Dylan has 4 more balls than Perry. Find the number of balls each boy has.
- Perry
- Dylan
Number of balls that Perry has = 1 u
Number of balls that Dylan has = 1 u + 4
Total number of balls
= 1 u + 1 u + 4
= 2 u + 4
2 u + 4 = 16
2 u = 16 - 4 = 12
1 u = 12 ÷ 2 = 6
(a)
Number of balls that Perry has
= 1 u
= 6
(b)
Number of balls that Dylan has
= 1 u + 4
= 6 + 4
= 10
Answer(s): (a) 6; (b) 10
