Adam spends $29 and buys some stickers and marbles.
Each marble is $2 and each sticker is $5.
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 5
= $15
(b)
Cost of 1 marble and 1 sticker
= 2 + 5
= $7
(c)
Cost of the stickers and marbles (excluding the 3 extra stickers)
= 29 - 15
= $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) $15; (b) $7; (c) 5
