Purchases= 137,000 pounds

Explanation:

Giving the following information:

Production= 20,000 pairs of skis.

Required material per unit= 7 pounds

Beginning inventory= 21,000 pounds

Desired ending inventory= 18,000 pounds.

To calculate the direct material purchase, we need to use the following formula:

Purchases= production + desired ending inventory - beginning inventory

Production= 20,000*7= 140,000 pounds

Purchases= 140,000 + 18,000 - 21,000

Purchases= 137,000 pounds
