Adam spends $36 and buys some stickers and marbles.
Each marble is $4 and each sticker is $3.
He buys 5 more stickers than marbles.
- What is the cost of the 5 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 5 more stickers
= 5 x 3
= $15
(b)
Cost of 1 marble and 1 sticker
= 4 + 3
= $7
(c)
Cost of the stickers and marbles (excluding the 5 extra stickers)
= 36 - 15
= $21
Number of sets of 1 marble and 1 sticker
= 21 ÷ 7
= 3
Number of stickers that Adam buys
= 3 + 5
= 8
Answer(s): (a) $15; (b) $7; (c) 8
