Adam spends $33 and buys some stickers and marbles.
Each marble is $3 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
= 3 + 4
= $7
(c)
Cost of the stickers and marbles (excluding the 3 extra stickers)
= 33 - 12
= $21
Number of sets of 1 marble and 1 sticker
= 21 ÷ 7
= 3
Number of stickers that Adam buys
= 3 + 3
= 6
Answer(s): (a) $12; (b) $7; (c) 6
