Archie had 239 cards more than Tammy. Given that they have a total of 425 cards,
- how many cards did Tammy have?
- how many cards did Archie have?
(a)
Number of cards that Archie that = 1 u + 239
Number of cards that Tammy had = 1 u
Total number of cards
= 1 u + 239 + 1 u
= 2 u + 239
2 u + 239 = 425
2 u = 425 - 239
2 u = 186
1 u = 186 ÷ 2 = 93
Number of cards that Tammy had
= 1 u
= 93
(b)
Number of cards that Archie had
= 1 u + 239
= 93 + 239
= 332
Answer(s): (a) 93; (b) 332
