Adam spends $40 and buys some beads and marbles.
Each marble is $2 and each bead is $4.
He buys 4 more beads than marbles.
- What is the cost of the 4 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 4 more beads
= 4 x 4
= $16
(b)
Cost of 1 marble and 1 bead
= 2 + 4
= $6
(c)
Cost of the beads and marbles (excluding the 4 extra beads)
= 40 - 16
= $24
Number of sets of 1 marble and 1 bead
= 24 ÷ 6
= 4
Number of beads that Adam buys
= 4 + 4
= 8
Answer(s): (a) $16; (b) $6; (c) 8
