Adam spends $24 and buys some marbles and stickers.
Each sticker is $2 and each marble is $5.
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 5
= $10
(b)
Cost of 1 sticker and 1 marble
= 2 + 5
= $7
(c)
Cost of the marbles and stickers (excluding the 2 extra marbles)
= 24 - 10
= $14
Number of sets of 1 sticker and 1 marble
= 14 ÷ 7
= 2
Number of marbles that Adam buys
= 2 + 2
= 4
Answer(s): (a) $10; (b) $7; (c) 4
