Explanation:

Step1: Calculate oil - change commission

Commission from oil changes = 3.00% of $2,500.00 = 0.03×2500=\$75$

Step2: Calculate tune - up commission

Commission from tune - ups = 5.00% of $4,500.00 = 0.05×4500=\$225$

Step3: Calculate auto - parts sales commission

Commission from auto - parts sales = 6.25% of $28,200.00 = 0.0625×28200=\$1762.5$

Step4: Calculate total commission

Total commission = 75 + 225+1762.5=\$2062.5$

Step5: Calculate gross pay

Since the minimum salary is $2,450.00 and the total commission $2062.5<2450$, the gross pay is the minimum salary. So the gross pay is $\$2450$.

Answer:

B. $2,450.00$
