Adam buys some stickers for his friends.
If he gives each of them 5 stickers, he has 2 stickers left.
If he gives each of them 8 stickers, he needs another 22.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 2 + 22
= 24
Small difference
= 8 - 5
= 3
Number of friends that Adam gives to
= 24 ÷ 3
= 8
(b)
Number of stickers that Adam buys
= 8 x 5 + 2
= 40 + 2
= 42
Answer(s): (a) 8; (b) 42
