Adam spends $34 and buys some marbles and stickers.
Each sticker is $4 and each marble is $3.
He buys 2 more marbles than stickers.
- What is the cost of the 2 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 2 more marbles
= 2 x 3
= $6
(b)
Cost of 1 sticker and 1 marble
= 4 + 3
= $7
(c)
Cost of the marbles and stickers (excluding the 2 extra marbles)

Number of sets of 1 sticker and 1 marble
= 28 ÷ 7
= 4
Number of marbles that Adam buys
= 4 + 2
= 6
Answer(s): (a) $6; (b) $7; (c) 6
