Adam spends $38 and buys some stickers and marbles.
Each marble is $2 and each sticker is $4.
He buys 5 more stickers than marbles.
- What is the cost of the 5 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 5 more stickers
= 5 x 4
= $20
(b)
Cost of 1 marble and 1 sticker
= 2 + 4
= $6
(c)
Cost of the stickers and marbles (excluding the 5 extra stickers)
= 38 - 20
= $18
Number of sets of 1 marble and 1 sticker
= 18 ÷ 6
= 3
Number of stickers that Adam buys
= 3 + 5
= 8
Answer(s): (a) $20; (b) $6; (c) 8
