Adam spends $22 and buys some beads and marbles.
Each marble is $3 and each bead is $4.
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 4
= $8
(b)
Cost of 1 marble and 1 bead
= 3 + 4
= $7
(c)
Cost of the beads and marbles (excluding the 2 extra beads)
= 22 - 8
= $14
Number of sets of 1 marble and 1 bead
= 14 ÷ 7
= 2
Number of beads that Adam buys
= 2 + 2
= 4
Answer(s): (a) $8; (b) $7; (c) 4
