Final answer:
The change in Howard Nets & Co.'s inventories is a decrease of $1,850 and they contributed $114,850 to GDP this year by their sales.
Step-by-step explanation:
The change in Howard Nets & Co.'s inventories is calculated by taking this year's ending inventory and subtracting last year's inventory. The company produced $115,000 worth of basketball nets and sold $114,850, so the ending inventory for this year would be the produced amount minus the sold amount, which equals $150 of inventory. This means that the change in inventory is $150 - $2,000 = -$1,850 (a decrease in inventory).
Next, to calculate the contribution to Gross Domestic Product (GDP), we consider the total sales. GDP measures the value of final goods and services produced over a period of time. For Howard Nets & Co., the contribution to GDP would be their sales which is $114,850 for this year.
