Adam spends $30 and buys some marbles and stickers.
Each sticker is $3 and each marble is $2.
He buys 5 more marbles than stickers.
- What is the cost of the 5 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 5 more marbles
= 5 x 2
= $10
(b)
Cost of 1 sticker and 1 marble
= 3 + 2
= $5
(c)
Cost of the marbles and stickers (excluding the 5 extra marbles)
= 30 - 10
= $20
Number of sets of 1 sticker and 1 marble
= 20 ÷ 5
= 4
Number of marbles that Adam buys
= 4 + 5
= 9
Answer(s): (a) $10; (b) $5; (c) 9
