Question 3 a) On March 1st, Valentina had six paddleboards ($500 cost). Each Monday this month (March 7th,
14th, 21st, and 28th), Valentina purchased six paddleboards from her supplier. The price increased to
$510 on March 12th, but dropped to $505 on March 28th. Valentina sold one paddleboard in week one
(March 1st to 7th), eight in week two, six in week three, and five in week four. Assuming the selling price
was $800 per paddleboard and Valentina uses the moving-weighted-average method, what was her
gross margin for March? Make all necessary journal entries and SHOW YOUR WORK!

March 1st   Beginning inventory  6     $500       $3,000     $3,000          

March 7th  Purchases                  6     $500       $3,000     $6,000 ($3,000 + $3,000)

Week 1       Cost of Sales             -1      $500         $500    $5,500 ($6,000 - $500)

March 14th Purchases                 6       $510      $3,060     $8,560 ($5,500 + $3,060)

Week 2      Cost of Sales           -8       $504      $4,032    $4,528 ($8,560 - $4,032)      

March 21st Purchases                6       $510      $3,060     $7,588 ($4,528 + $3,060)

Week 3    Cost of Sales            -6       $506     $3,036     $4,552 ($7,588 - $3,036)

March 28th  Purchases             6       $505     $3,030     $7,582 ($4,552 + $3,030)

Week 4       Cost of Sales        -5       $505     $2,525    $5,057 ($7,82 - $2,525)

Sales revenue = 20 x $800 = $16,000

Cost of goods sold = Cost of goods available – Ending inventory

= $10,093 ($15,150 - $5,057)

Gross margin for March = $5,907 ($16,000 - $10,093)

Week Four Cost Sales             -5        $510  $2,550        $5,070 ($7,620 - $2,550)

Sales revenue = 20 x $800 = $16,000

Cost of goods sold = Cost of goods available – Ending inventory

= $10,080 ($15,150 - $5,070)

Gross margin for March = $5,920 ($16,000 - $10,080)
