Adam spends $40 and buys some marbles and beads.
Each bead is $4 and each marble is $2.
He buys 2 more marbles than beads.
- What is the cost of the 2 more marbles?
- What is the cost of 1 bead and 1 marble?
- How many marbles does he buy?
(a)
Cost that Adam pays for the 2 more marbles
= 2 x 2
= $4
(b)
Cost of 1 bead and 1 marble
= 4 + 2
= $6
(c)
Cost of the marbles and beads (excluding the 2 extra marbles)
= 40 - 4
= $36
Number of sets of 1 bead and 1 marble
= 36 ÷ 6
= 6
Number of marbles that Adam buys
= 6 + 2
= 8
Answer(s): (a) $4; (b) $6; (c) 8
