Adam spends $48 and buys some beads and marbles.
Each marble is $2 and each bead is $4.
He buys 3 more beads than marbles.
- What is the cost of the 3 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 3 more beads
= 3 x 4
= $12
(b)
Cost of 1 marble and 1 bead
= 2 + 4
= $6
(c)
Cost of the beads and marbles (excluding the 3 extra beads)
= 48 - 12
= $36
Number of sets of 1 marble and 1 bead
= 36 ÷ 6
= 6
Number of beads that Adam buys
= 6 + 3
= 9
Answer(s): (a) $12; (b) $6; (c) 9
