Adam spends $24 and buys some beads and marbles.
Each marble is $5 and each bead is $2.
He buys 5 more beads than marbles.
- What is the cost of the 5 more beads?
- What is the cost of 1 marble and 1 bead?
- How many beads does he buy?
(a)
Cost that Adam pays for the 5 more beads
= 5 x 2
= $10
(b)
Cost of 1 marble and 1 bead
= 5 + 2
= $7
(c)
Cost of the beads and marbles (excluding the 5 extra beads)
= 24 - 10
= $14
Number of sets of 1 marble and 1 bead
= 14 ÷ 7
= 2
Number of beads that Adam buys
= 2 + 5
= 7
Answer(s): (a) $10; (b) $7; (c) 7
