Bryan had 267 coins less than Linda. Given that they have a total of 639 coins,
- How many coins did Linda have?
- How many coins did Bryan have?
(a)
Number of coins that Linda had = 1 u
Number of coins that Bryan had = 1 u - 267
Total number of coins
= 1 u + 1 u - 267
= 2 u - 267
2 u - 267 = 639
2 u = 639 + 267
2 u = 906
1 u = 906 ÷ 2 = 453
Number of coins that Linda had
= 1 u
= 453
(b)
Number of coins that Bryan had
= 1 u - 267
= 453 - 267
= 186
Answer(s): (a) 453; (b) 186
