Adam spends $22 and buys some marbles and stickers.
Each sticker is $5 and each marble is $2.
He buys 4 more marbles than stickers.
- What is the cost of the 4 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 4 more marbles
= 4 x 2
= $8
(b)
Cost of 1 sticker and 1 marble
= 5 + 2
= $7
(c)
Cost of the marbles and stickers (excluding the 4 extra marbles)
= 22 - 8
= $14
Number of sets of 1 sticker and 1 marble
= 14 ÷ 7
= 2
Number of marbles that Adam buys
= 2 + 4
= 6
