Based on past experience, Kzinski has found that approximately 10% of mixers are returned for repair or replacement. The average cost to ship a mixer to Boston is $60.

The following transactions take place in 2020 and 2021.

1.Atotal of 30 mixers are sold in 2020.

2.Four of the mixers sold in 2020 are returned for repair in 2021. The total shipping cost for returning these four mixers to Boston is $210.

3.A total of 40 mixers are sold in 2021.

4.Two of the mixers sold in 2021 are returned for repair in 2021. The total shipping cost for returning these two mixers to Boston is $55.

How would I make a summary journal entry (or entries) to record the shipment of the six mixers (four from the 2020 sales and two from the 2021 sales) for warranty repair in 2021.
