Adam buys some stickers for his friends.
If he gives each of them 2 stickers, he has 6 stickers left.
If he gives each of them 4 stickers, he needs another 8.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 6 + 8
= 14
Small difference
= 4 - 2
= 2
Number of friends that Adam gives to
= 14 ÷ 2
= 7
(b)
Number of stickers that Adam buys
= 7 x 2 + 6
= 14 + 6
= 20
Answer(s): (a) 7; (b) 20
