Adam spends $47 and buys some beads and marbles.
Each marble is $3 and each bead is $4.
He buys 3 more beads than marbles.
- What is the cost of the 3 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 3 more beads
= 3 x 4
= $12
(b)
Cost of 1 marble and 1 bead
= 3 + 4
= $7
(c)
Cost of the beads and marbles (excluding the 3 extra beads)
= 47 - 12
= $35
Number of sets of 1 marble and 1 bead
= 35 ÷ 7
= 5
Number of beads that Adam buys
= 5 + 3
= 8
Answer(s): (a) $12; (b) $7; (c) 8
