Question

Janice published a novel. Last month the book sold 1307 copies, earning Janice a total of $1408.4. This month the book sold 1409 copies. How much should Janice expect to receive in royalties this month?

Answer 1

$1518.31

Explanation:

Books sold = 1307

Earning from 1307 copies = $1408.4

Earning from one copy:

• 1408.4/1307

Earning from 1409 copies expected:

• 1409*1408.4/1307 ≈ 1518.31
