Adam spends $25 and buys some marbles and stickers.
Each sticker is $5 and each marble is $2.
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 2
= $4
(b)
Cost of 1 sticker and 1 marble
= 5 + 2
= $7
(c)
Cost of the marbles and stickers (excluding the 2 extra marbles)
= 25 - 4
= $21
Number of sets of 1 sticker and 1 marble
= 21 ÷ 7
= 3
Number of marbles that Adam buys
= 3 + 2
= 5
Answer(s): (a) $4; (b) $7; (c) 5
