The weighted average hourly rate is calculated by multiplying each group's hourly rate by the number of individuals in that group, summing these products, and then dividing by the total number of individuals. For the junior engineers: 8 * $24.75 = $198. For the senior engineers: 5 * $39.49 = $197.45. For the manager: 1 * $47.24 = $47.24. Summing these gives $442.69. Dividing by the total number of individuals (8 + 5 + 1 = 14) gives $442.69 / 14 = $31.62.
