Adam spends $23 and buys some stickers and marbles.
Each marble is $4 and each sticker is $3.
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 3
= $9
(b)
Cost of 1 marble and 1 sticker
= 4 + 3
= $7
(c)
Cost of the stickers and marbles (excluding the 3 extra stickers)
= 23 - 9
= $14
Number of sets of 1 marble and 1 sticker
= 14 ÷ 7
= 2
Number of stickers that Adam buys
= 2 + 3
= 5
Answer(s): (a) $9; (b) $7; (c) 5
