Adam spends $49 and buys some marbles and beads.
Each bead is $2 and each marble is $3.
He buys 3 more marbles than beads.
- What is the cost of the 3 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 3 more marbles
= 3 x 3
= $9
(b)
Cost of 1 bead and 1 marble
= 2 + 3
= $5
(c)
Cost of the marbles and beads (excluding the 3 extra marbles)
= 49 - 9
= $40
Number of sets of 1 bead and 1 marble
= 40 ÷ 5
= 8
Number of marbles that Adam buys
= 8 + 3
= 11
Answer(s): (a) $9; (b) $5; (c) 11
