Evan Engineering Group receives royalties on a technical manual written by two of its engineers and sold to a publishing company. Royalties are 10% of net sales, receivable on October 1 for sales in January through June and on April 1 for sales in July through December of the prior year. Sales of the manual began in July 2015, and Evan accrued royalty revenue on $30,010 of sales at December 31, 2015. Evan received royalties of $2,613 on April 1, 2016. On October 1, 2016 Evan received royalties of $4,631. The 2nd half of 2016 sales were estimated to be $43,220 What is Evan's 2016 royalty revenue

$8,565

Explanation:

Sales revenue of the year 2015 = $30,010

Accrued royalty revenue on December 31, 2015 = 30,010 x 10%

= $3,001

Evan received royalties of $2,613 on April 1, 2016.

Hence, royalty receivable for the year ended December 31, 2015 = 3,001- 2,613

= $388

On October 1, 2016, Evan received royalties of $4,631.

Thus, royalty received for the first half of the year 2016 = 4,631 - 388

= $4,243

The 2nd half of 2016 sales were estimated to be $43,220

Hence, royalty for the second half of the year 2016 = 43,220 x 10%

= $4,322

Evan's 2016 royalty revenue = Royalty revenue for the first half + Royalty revenue for the second half

= 4,243 + 4,322

= $8,565
