Flynn and Vincent have 20 marbles altogether. Flynn has 4 more marbles than Vincent. Find the number of marbles each boy has.
- Vincent
- Flynn
Number of marbles that Vincent has = 1 u
Number of marbles that Flynn has = 1 u + 4
Total number of marbles
= 1 u + 1 u + 4
= 2 u + 4
2 u + 4 = 20
2 u = 20 - 4 = 16
1 u = 16 ÷ 2 = 8
(a)
Number of marbles that Vincent has
= 1 u
= 8
(b)
Number of marbles that Flynn has
= 1 u + 4
= 8 + 4
= 12
Answer(s): (a) 8; (b) 12
