Explanation:

a) Data and Calculations:

Net sales                                                       $ 229,234 $ 215,639

Cost of sales                                                      141,048      131,376

Research and development expenses               11,581       10,045

Selling, general, and administrative expenses  15,261       14,194

Operating income                                                         ?              ?

Other income, net                                                         ?       1,348

Provision for income taxes                                 15,738               ?

Net income                                                      $ 48,351  $ 45,687

Operating income = Net sales minus (Cost of sales + R&D expenses, + Selling, general, and administrative expenses)

Other income, net = Net income + Provision for income taxes - Operating income

Provision for income taxes = Operating income + Other income - Net income

the answer would be price fixing, hope it
