The unnecessary information in the problem is the salesperson's weekly salary of 350. The extra money = 180

Work Step by Step

Weekly salary of salesperson = 350 Amount received per item for every item sold more than 200 = 15 Number of items sold = 212 Number of items sold more than 200 = 212-200 = 12 So, to find out the extra money he received we don't need the information about the weekly salary. Therefore, extra money he received = 12 x 15 = 180
