Sheffield Company sells automatic can openers under a 75-day warranty for defective merchandise. Based on past experience, Sheffield estimates that 3% of the units sold will become defective during the warranty period. Management estimates that the average cost of replacing or repairing a defective unit is $20. The units sold and units defective that occurred during the last 2 months of 2020 are as follows. (See images below)

I'm almost certain that the only accounts that need to be listed in this 3 entries would be Warranty Expense, Warranty Liability and Repair Parts but I do not know this for a fact.

Warranty Expense = (30800 + 32800)(0.03)(20) = 38160 So I would debit 38160 to Warranty Expense then credit 38160 to Warranty Liability ? Below is a couple images showing the question in its entirety.

I could really use help with how the figures are being calculated.

I did see similar questions, however, the explanations were unclear.
