Ivan had 221 stickers more than Roshel. Given that they have a total of 521 stickers,
- how many stickers did Roshel have?
- how many stickers did Ivan have?
(a)
Number of stickers that Ivan that = 1 u + 221
Number of stickers that Roshel had = 1 u
Total number of stickers
= 1 u + 221 + 1 u
= 2 u + 221
2 u + 221 = 521
2 u = 521 - 221
2 u = 300
1 u = 300 ÷ 2 = 150
Number of stickers that Roshel had
= 1 u
= 150
(b)
Number of stickers that Ivan had
= 1 u + 221
= 150 + 221
= 371
Answer(s): (a) 150; (b) 371
