Suppose a Robak store in Ottawa, Ontario, ended April 2020 with 850,000 units of merchandise that cost an average of $7 each. Suppose the store then sold 650,000 units for $5.0 million during May. Further, assume the store made two large purchases during May as follows: Required May 11 26 90,000 units @ $ 6 350,000 units @ $ = $ 540,000 5 = $ 1,750,000 1. At May 31, the store manager needs to know the store's gross profit under both FIFO and weighted-average cost. Supply this information. Robak uses the periodic inventory system 2. What caused the FIFO and weighted-average cost gross profit figures to differ? Requirement 1. At May 31, the store manager needs to know the store's gross profit under both FIFO and weighted-average cost. Supply this information. Robak uses the periodic inventory system. (Round all calculations to one decimal place.) Millions Gross profit FIFO Weighted- Average-Cost
