Answer: $375
Step-by-step explanation:
Condition of Ben's weekly earnings go like as following equation:
Ben gets = Salary + 3% of sales
When he got $471 and sales were $3200
Then the equation becomes:
471 = Salary + 3% of 3200
471 = Salary + 3200x3/100
471 = Salary + 32x3
471 = Salary + 96
471-96 = Salary
375 = Salary
Salary = $375
