Mr Lim had some stickers and stamps for his class. The number of stickers was half as many as the number of stamps. After each pupil in the class had received 3 stickers and 8 stamps from Mr Lim, he had 39 stickers and 2 stamps left. What was the total number of stickers and stamps Mr Lim had at first?

Thanks

[/p]

stamps = 2u
stickers = 1u
total = 3u

No of students = 1p
3p + 39 = 1u -> 6p + 78 = 2u
8p + 2 = 2u

6p + 78 = 8p + 2

2p = 76
1p = 38
1u =38 * 3 + 39 = 153
Total = 153 * 3 = 459
hope this helps!
