Goddard Company has used the FIFO method of inventory valuation since it began operations in 2015. Goddard decided to change to the average cost method for determining inventory costs at the beginning of 2018. The following schedule shows year-end inventory balances under the FIFO and average cost methods: Year FIFO Average Cost 2015 $ 46,500 $ 57,000 2016 82,500 72,500 2017 89,000 82,500 Required: 1. Ignoring income taxes, prepare the 2018 journal entry to adjust the accounts to reflect the average cost method. 2. How much higher or lower would cost of goods sold be in the 2017 revised income statement?
