Adam spends $32 and buys some marbles and stickers.
Each sticker is $2 and each marble is $4.
He buys 5 more marbles than stickers.
- What is the cost of the 5 more marbles?
- What is the cost of 1 sticker and 1 marble?
- How many marbles does he buy?
(a)
Cost that Adam pays for the 5 more marbles
= 5 x 4
= $20
(b)
Cost of 1 sticker and 1 marble
= 2 + 4
= $6
(c)
Cost of the marbles and stickers (excluding the 5 extra marbles)
= 32 - 20
= $12
Number of sets of 1 sticker and 1 marble
= 12 ÷ 6
= 2
Number of marbles that Adam buys
= 2 + 5
= 7
Answer(s): (a) $20; (b) $6; (c) 7
