Adam spends $40 and buys some stickers and marbles.
Each marble is $4 and each sticker is $3.
He buys 4 more stickers than marbles.
- What is the cost of the 4 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 4 more stickers
= 4 x 3
= $12
(b)
Cost of 1 marble and 1 sticker
= 4 + 3
= $7
(c)
Cost of the stickers and marbles (excluding the 4 extra stickers)
= 40 - 12
= $28
Number of sets of 1 marble and 1 sticker
= 28 ÷ 7
= 4
Number of stickers that Adam buys
= 4 + 4
= 8
Answer(s): (a) $12; (b) $7; (c) 8
