Question

as a payroll coordinator, you compute the weekly pay for contractors. last week, a contractor worked 15 hours at $18 per hour, 10 hours at $12 per hour, and 6 hours at $25 per hour. what is the weighted - average hourly pay for this contractor?
a $9.82
b $10.33
c $14.33
d $17.42
e $18.33

Explanation:

Step1: Calculate total pay

$15\times18 + 10\times12+6\times25=270 + 120+150 = 540$

Step2: Calculate total hours

$15 + 10+6=31$

Step3: Calculate weighted - average hourly pay

$\frac{540}{31}\approx17.42$

Answer:

D. $17.42$
