Adam spends $28 and buys some marbles and beads.
Each bead is $5 and each marble is $3.
He buys 4 more marbles than beads.
- What is the cost of the 4 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 4 more marbles
= 4 x 3
= $12
(b)
Cost of 1 bead and 1 marble
= 5 + 3
= $8
(c)
Cost of the marbles and beads (excluding the 4 extra marbles)
= 28 - 12
= $16
Number of sets of 1 bead and 1 marble
= 16 ÷ 8
= 2
Number of marbles that Adam buys
= 2 + 4
= 6
Answer(s): (a) $12; (b) $8; (c) 6
