Owen and Bryan have 15 balls altogether. Owen has 7 more balls than Bryan. Find the number of balls each boy has.
- Bryan
- Owen
Number of balls that Bryan has = 1 u
Number of balls that Owen has = 1 u + 7
Total number of balls
= 1 u + 1 u + 7
= 2 u + 7
2 u + 7 = 15
2 u = 15 - 7 = 8
1 u = 8 ÷ 2 = 4
(a)
Number of balls that Bryan has
= 1 u
= 4
(b)
Number of balls that Owen has
= 1 u + 7
= 4 + 7
= 11
Answer(s): (a) 4; (b) 11
