Adam spends $50 and buys some marbles and stickers.
Each sticker is $3 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
= 3 + 5
= $8
(c)
Cost of the marbles and stickers (excluding the 2 extra marbles)
= 50 - 10
= $40
Number of sets of 1 sticker and 1 marble
= 40 ÷ 8
= 5
Number of marbles that Adam buys
= 5 + 2
= 7
Answer(s): (a) $10; (b) $8; (c) 7
