Adam spends $48 and buys some stickers and marbles.
Each marble is $5 and each sticker is $4.
He buys 3 more stickers than marbles.
- What is the cost of the 3 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 3 more stickers
= 3 x 4
= $12
(b)
Cost of 1 marble and 1 sticker
= 5 + 4
= $9
(c)
Cost of the stickers and marbles (excluding the 3 extra stickers)
= 48 - 12
= $36
Number of sets of 1 marble and 1 sticker
= 36 ÷ 9
= 4
Number of stickers that Adam buys
= 4 + 3
= 7
Answer(s): (a) $12; (b) $9; (c) 7
