Adam buys some stickers for his friends.
If he gives each of them 10 stickers, he needs another 3.
If he gives each of them 14 stickers, he needs another 19.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 19 - 3
= 16
Small difference
= 14 - 10
= 4
Number of friends that Adam gives to
= 16 ÷ 4
= 4
(b)
Number of stickers that Adam buys
= 4 x 10 - 3
= 40 - 3
= 37
Answer(s): (a) 4; (b) 37
