Adam buys some stickers for his friends.
If he gives each of them 3 stickers, he has 2 stickers left.
If he gives each of them 7 stickers, he needs another 22.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 2 + 22
= 24
Small difference
= 7 - 3
= 4
Number of friends that Adam gives to
= 24 ÷ 4
= 6
(b)
Number of stickers that Adam buys
= 6 x 3 + 2
= 18 + 2
= 20
Answer(s): (a) 6; (b) 20
