Will and Seth have 20 balls altogether. Will has 2 more balls than Seth. Find the number of balls each boy has.
- Seth
- Will
Number of balls that Seth has = 1 u
Number of balls that Will has = 1 u + 2
Total number of balls
= 1 u + 1 u + 2
= 2 u + 2
2 u + 2 = 20
2 u = 20 - 2 = 18
1 u = 18 ÷ 2 = 9
(a)
Number of balls that Seth has
= 1 u
= 9
(b)
Number of balls that Will has
= 1 u + 2
= 9 + 2
= 11
Answer(s): (a) 9; (b) 11
