Warren had 242 marbles more than Olivia. Given that they have a total of 406 marbles,
- how many marbles did Olivia have?
- how many marbles did Warren have?
(a)
Number of marbles that Warren that = 1 u + 242
Number of marbles that Olivia had = 1 u
Total number of marbles
= 1 u + 242 + 1 u
= 2 u + 242
2 u + 242 = 406
2 u = 406 - 242
2 u = 164
1 u = 164 ÷ 2 = 82
Number of marbles that Olivia had
= 1 u
= 82
(b)
Number of marbles that Warren had
= 1 u + 242
= 82 + 242
= 324
Answer(s): (a) 82; (b) 324
