Question 1 Washing Company sells dishwashers for $ 900 each, which includes a 1-year warranty that requires the company to perform periodic services and to replace defective parts. During 2019, Washing sold 1,000 dishwashers on account, not for cash. Based on experience, the company has estimated the total 1-year warranty costs at $ 30 for parts and $ 40 for labour. (Assume all sales were made on December 31, 2019.) In 2020, Washing Company incurred actual warranty costs relative to 2019 dishwasher sales of $ 5,000 for parts and $ 6,000 for labour. The fair value of providing a 1-year warranty alone is $ 120 per unit. Required: a. Using the expense warranty approach, prepare the entries to reflect the above transactions (accrual method) for 2019 and 2020. b. Using the revenue approach, prepare the entries to reflect the above transactions (accrual method) for 2019 and 2020
