Adam spends $39 and buys some marbles and stickers.
Each sticker is $5 and each marble is $3.
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 3
= $15
(b)
Cost of 1 sticker and 1 marble
= 5 + 3
= $8
(c)
Cost of the marbles and stickers (excluding the 5 extra marbles)
= 39 - 15
= $24
Number of sets of 1 sticker and 1 marble
= 24 ÷ 8
= 3
Number of marbles that Adam buys
= 3 + 5
= 8
Answer(s): (a) $15; (b) $8; (c) 8
