Adam spends $43 and buys some beads and marbles.
Each marble is $4 and each bead is $3.
He buys 5 more beads than marbles.
- What is the cost of the 5 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 5 more beads
= 5 x 3
= $15
(b)
Cost of 1 marble and 1 bead
= 4 + 3
= $7
(c)
Cost of the beads and marbles (excluding the 5 extra beads)
= 43 - 15
= $28
Number of sets of 1 marble and 1 bead
= 28 ÷ 7
= 4
Number of beads that Adam buys
= 4 + 5
= 9
Answer(s): (a) $15; (b) $7; (c) 9
