Ethan had 250 stickers less than Betty. Given that they have a total of 664 stickers,
- How many stickers did Betty have?
- How many stickers did Ethan have?
(a)
Number of stickers that Betty had = 1 u
Number of stickers that Ethan had = 1 u - 250
Total number of stickers
= 1 u + 1 u - 250
= 2 u - 250
2 u - 250 = 664
2 u = 664 + 250
2 u = 914
1 u = 914 ÷ 2 = 457
Number of stickers that Betty had
= 1 u
= 457
(b)
Number of stickers that Ethan had
= 1 u - 250
= 457 - 250
= 207
Answer(s): (a) 457; (b) 207
