Can you please help me with this accounting question ?

A company sells leaf blowers for $170 each. Each unit has a 3 year warranty that covers replacement of defective parts. It is estimated that 4% of all leaf blowers sold will be returned under the warranty at an average cost of $30 each. During October, the company sold 400,000 leaf blowers. 800 leaf blowers were serviced under the warranty during October at a total cost of $25,000. The balance in the Estimated Warranty Liability account on October 1 was $12,500. What is the company's warranty expense for the month of October?
