1 sticker costs $5.
1 box of 45 stickers costs $15.
Adam needs 56 stickers.
- What is the minimum number of boxs that Adam should buy?
- How much will Adam spend?
(a)
Sets of 45 stickers
= 56 ÷ 45
= 1 r 11
Amount that Adam has to spend to buy 11 stickers
= 11 x 5
= $55
To buy 11 stickers at $55 is more expensive than 45 stickers at $15.
Minimum number of boxs that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 boxs
= 2 x 15
= $30
Answer(s): (a) 2; (b) $30
