Adam spends $29 and buys some stickers and marbles.
Each marble is $4 and each sticker is $5.
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 5
= $20
(b)
Cost of 1 marble and 1 sticker
= 4 + 5
= $9
(c)
Cost of the stickers and marbles (excluding the 4 extra stickers)
= 29 - 20
= $9
Number of sets of 1 marble and 1 sticker
= 9 ÷ 9
= 1
Number of stickers that Adam buys
= 1 + 4
= 5
Answer(s): (a) $20; (b) $9; (c) 5
