Adam spends $36 and buys some marbles and stickers.
Each sticker is $4 and each marble is $2.
He buys 3 more marbles than stickers.
- What is the cost of the 3 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 3 more marbles
= 3 x 2
= $6
(b)
Cost of 1 sticker and 1 marble
= 4 + 2
= $6
(c)
Cost of the marbles and stickers (excluding the 3 extra marbles)
= 36 - 6
= $30
Number of sets of 1 sticker and 1 marble
= 30 ÷ 6
= 5
Number of marbles that Adam buys
= 5 + 3
= 8
Answer(s): (a) $6; (b) $6; (c) 8
