Adam spends $22 and buys some beads and marbles.
Each marble is $2 and each bead is $3.
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 3
= $12
(b)
Cost of 1 marble and 1 bead
= 2 + 3
= $5
(c)
Cost of the beads and marbles (excluding the 4 extra beads)
= 22 - 12
= $10
Number of sets of 1 marble and 1 bead
= 10 ÷ 5
= 2
Number of beads that Adam buys
= 2 + 4
= 6
Answer(s): (a) $12; (b) $5; (c) 6
