To find the constant of proportionality, we need to divide the total amount paid by the total number of hours worked.
The total amount paid is $87 + $65.25 = $152.25.
The total number of hours worked is 12 + 9 = 21.
Thus, the constant of proportionality is $152.25 divided by 21, which equals $7.25.
Therefore, the correct answer is B) 7.25.
