Adam spends $20 and buys some marbles and stickers.
Each sticker is $2 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
= 2 + 3
= $5
(c)
Cost of the marbles and stickers (excluding the 5 extra marbles)
= 20 - 15
= $5
Number of sets of 1 sticker and 1 marble
= 5 ÷ 5
= 1
Number of marbles that Adam buys
= 1 + 5
= 6
Answer(s): (a) $15; (b) $5; (c) 6
