Andy and Seth have 14 marbles altogether. Andy has 8 more marbles than Seth. Find the number of marbles each boy has.
- Seth
- Andy
Number of marbles that Seth has = 1 u
Number of marbles that Andy has = 1 u + 8
Total number of marbles
= 1 u + 1 u + 8
= 2 u + 8
2 u + 8 = 14
2 u = 14 - 8 = 6
1 u = 6 ÷ 2 = 3
(a)
Number of marbles that Seth has
= 1 u
= 3
(b)
Number of marbles that Andy has
= 1 u + 8
= 3 + 8
= 11
Answer(s): (a) 3; (b) 11
