Adam spends $26 and buys some marbles and beads.
Each bead is $4 and each marble is $2.
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 2
= $8
(b)
Cost of 1 bead and 1 marble
= 4 + 2
= $6
(c)
Cost of the marbles and beads (excluding the 4 extra marbles)
= 26 - 8
= $18
Number of sets of 1 bead and 1 marble
= 18 ÷ 6
= 3
Number of marbles that Adam buys
= 3 + 4
= 7
Answer(s): (a) $8; (b) $6; (c) 7
