Riordan had 240 cards more than Ivory. Given that they have a total of 534 cards,
- how many cards did Ivory have?
- how many cards did Riordan have?
(a)
Number of cards that Riordan that = 1 u + 240
Number of cards that Ivory had = 1 u
Total number of cards
= 1 u + 240 + 1 u
= 2 u + 240
2 u + 240 = 534
2 u = 534 - 240
2 u = 294
1 u = 294 ÷ 2 = 147
Number of cards that Ivory had
= 1 u
= 147
(b)
Number of cards that Riordan had
= 1 u + 240
= 147 + 240
= 387
Answer(s): (a) 147; (b) 387
