Adam spends $37 and buys some beads and marbles.
Each marble is $4 and each bead is $5.
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 5
= $10
(b)
Cost of 1 marble and 1 bead
= 4 + 5
= $9
(c)
Cost of the beads and marbles (excluding the 2 extra beads)
= 37 - 10
= $27
Number of sets of 1 marble and 1 bead
= 27 ÷ 9
= 3
Number of beads that Adam buys
= 3 + 2
= 5
Answer(s): (a) $10; (b) $9; (c) 5
