Adam spends $22 and buys some beads and marbles.
Each marble is $4 and each bead is $2.
He buys 2 more beads than marbles.
- What is the cost of the 2 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 2 more beads
= 2 x 2
= $4
(b)
Cost of 1 marble and 1 bead
= 4 + 2
= $6
(c)
Cost of the beads and marbles (excluding the 2 extra beads)
= 22 - 4
= $18
Number of sets of 1 marble and 1 bead
= 18 ÷ 6
= 3
Number of beads that Adam buys
= 3 + 2
= 5
Answer(s): (a) $4; (b) $6; (c) 5
