Answer
# Explanation:
## Step1: Identify the formula
Total pay = Hourly rate × Hours worked
## Step2: Substitute values
Total pay = $7.85\times18.75$
## Step3: Calculate
$7.85\times18.75 = 7.85\times(18 + 0.75)=7.85\times18+7.85\times0.75=(8 - 0.15)\times18+(8 - 0.15)\times0.75=(8\times18-0.15\times18)+(8\times0.75 - 0.15\times0.75)=(144 - 2.7)+(6 - 0.1125)=141.3+5.8875 = 147.1875\approx147.19$
# Answer:
C. $147.19$
