Step-by-step explanation:
you can find this out by dividing the total amount of money owed by how many people are paying, say for instance, you have 6 people paying $40 in total, divide 40 by 6 to get $6.67 (rounded to the nearest .01)
We know that P is 1700, plus 120 for every copy of the book he sells. As a result, P=120N+1700. If N=29, we have P=120*29+1700, or P=3480+1700, so P=5180.
