Adam spends $50 and buys some marbles and beads.
Each bead is $2 and each marble is $4.
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 4
= $8
(b)
Cost of 1 bead and 1 marble
= 2 + 4
= $6
(c)
Cost of the marbles and beads (excluding the 2 extra marbles)
= 50 - 8
= $42
Number of sets of 1 bead and 1 marble
= 42 ÷ 6
= 7
Number of marbles that Adam buys
= 7 + 2
= 9
Answer(s): (a) $8; (b) $6; (c) 9
