Simon had 248 marbles more than Irene. Given that they have a total of 536 marbles,
- how many marbles did Irene have?
- how many marbles did Simon have?
(a)
Number of marbles that Simon that = 1 u + 248
Number of marbles that Irene had = 1 u
Total number of marbles
= 1 u + 248 + 1 u
= 2 u + 248
2 u + 248 = 536
2 u = 536 - 248
2 u = 288
1 u = 288 ÷ 2 = 144
Number of marbles that Irene had
= 1 u
= 144
(b)
Number of marbles that Simon had
= 1 u + 248
= 144 + 248
= 392
Answer(s): (a) 144; (b) 392
