Luis and Reggie have 19 balls altogether. Luis has 1 more balls than Reggie. Find the number of balls each boy has.
- Reggie
- Luis
Number of balls that Reggie has = 1 u
Number of balls that Luis has = 1 u + 1
Total number of balls
= 1 u + 1 u + 1
= 2 u + 1
2 u + 1 = 19
2 u = 19 - 1 = 18
1 u = 18 ÷ 2 = 9
(a)
Number of balls that Reggie has
= 1 u
= 9
(b)
Number of balls that Luis has
= 1 u + 1
= 9 + 1
= 10
Answer(s): (a) 9; (b) 10
