Answer
Explanation:
Step1: Calculate commission from oil - changes
Commission from oil - changes = 3% of $2500=\frac{3}{100}\times2500 = 75$
Step2: Calculate commission from tune - ups
Commission from tune - ups = 5% of $4500=\frac{5}{100}\times4500 = 225$
Step3: Calculate commission from parts sales
Commission from parts sales = 6.25% of $28200=\frac{6.25}{100}\times28200= 1762.5$
Step4: Calculate total commission
Total commission = 75 + 225+1762.5 = 2062.5$
Step5: Calculate gross pay
Gross pay = Minimum salary+Total commission = 2450+2062.5 - 2450=2450$ (since the minimum salary of $2450$ is already guaranteed and the total commission calculation is just for illustration, but the pay is at least the minimum salary)
Answer:
B. $2,450.00$
