Adam buys some stickers for his friends.
If he gives each of them 3 stickers, he has 6 stickers left.
If he gives each of them 5 stickers, he needs another 10.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 6 + 10
= 16
Small difference
= 5 - 3
= 2
Number of friends that Adam gives to
= 16 ÷ 2
= 8
(b)
Number of stickers that Adam buys
= 8 x 3 + 6
= 24 + 6
= 30
Answer(s): (a) 8; (b) 30
