Ben had 214 marbles more than Joelle. Given that they have a total of 462 marbles,
- how many marbles did Joelle have?
- how many marbles did Ben have?
(a)
Number of marbles that Ben that = 1 u + 214
Number of marbles that Joelle had = 1 u
Total number of marbles
= 1 u + 214 + 1 u
= 2 u + 214
2 u + 214 = 462
2 u = 462 - 214
2 u = 248
1 u = 248 ÷ 2 = 124
Number of marbles that Joelle had
= 1 u
= 124
(b)
Number of marbles that Ben had
= 1 u + 214
= 124 + 214
= 338
Answer(s): (a) 124; (b) 338
