1 sticker costs $2.
1 box of 35 stickers costs $20.
Adam needs 86 stickers.
- What is the minimum number of boxs that Adam should buy?
- How much will Adam spend?
(a)
Sets of 35 stickers
= 86 ÷ 35
= 2 r 16
Amount that Adam has to spend to buy 16 stickers
= 16 x 2
= $32
To buy 16 stickers at $32 is more expensive than 35 stickers at $20.
Minimum number of boxs that Adam has to buy
= 2 + 1
= 3
(b)
Amount that Adam has to spend on 3 boxs
= 3 x 20
= $60
Answer(s): (a) 3; (b) $60
