Adam spends $50 and buys some stickers and marbles.
Each marble is $3 and each sticker is $5.
He buys 2 more stickers than marbles.
- What is the cost of the 2 more stickers?
- What is the cost of 1 marble and 1 sticker?
- How many stickers does he buy?
(a)
Cost that Adam pays for the 2 more stickers
= 2 x 5
= $10
(b)
Cost of 1 marble and 1 sticker
= 3 + 5
= $8
(c)
Cost of the stickers and marbles (excluding the 2 extra stickers)
= 50 - 10
= $40
Number of sets of 1 marble and 1 sticker
= 40 ÷ 8
= 5
Number of stickers that Adam buys
= 5 + 2
= 7
Answer(s): (a) $10; (b) $8; (c) 7
