Adam buys some stickers for his friends.
If he gives each of them 8 stickers, he has 3 stickers left.
If he gives each of them 12 stickers, he needs another 17.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 3 + 17
= 20
Small difference
= 12 - 8
= 4
Number of friends that Adam gives to
= 20 ÷ 4
= 5
(b)
Number of stickers that Adam buys
= 5 x 8 + 3
= 40 + 3
= 43
Answer(s): (a) 5; (b) 43
