Raeann, Samantha, Samuel and Noah share the same hobby of collecting beads. The average number of beads collected by the 4 friends is 29. Samantha collected 8 more beads than Samuel but 12 fewer beads than Raeann. Noah collected 4 beads fewer than Samuel. Find the average number of beads collected by Samantha, Samuel and Noah. Round off your answer to the nearest whole number.
Number of beads Samuel collected = 1 u
Number of beads Samantha collected = 1 u + 8
Number of beads Raeann collected = 1 u + 8 + 12 = 1 u + 20
Number of beads Noah collected = 1 u - 4

Total number of beads collected
= 4 x 29
= 116

Total number of beads collected in units
= 1 u + 1 u + 8 + 1 u + 20 + 1 u - 4
= 4 u + 24

4 u + 24 = 116
4 u = 116 - 24 = 92

1 u = 92 ÷ 4 = 23

Total number of beads collected by Samantha, Samuel and Noah
= 1 u + 8 + 1 u + 1 u - 4
= 3 u + 4
= 3 x 23 + 4
= 73

Average number of beads collected by Samantha, Samuel and Noah
= 73 ÷ 3
≈ 24 (Round off to the nearest whole number.)
