Adam spends $34 and buys some marbles and beads.
Each bead is $3 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
= 3 + 2
= $5
(c)
Cost of the marbles and beads (excluding the 2 extra marbles)
= 34 - 4
= $30
Number of sets of 1 bead and 1 marble
= 30 ÷ 5
= 6
Number of marbles that Adam buys
= 6 + 2
= 8
Answer(s): (a) $4; (b) $5; (c) 8
