Step-by-step explanation:

Modify the program

To modify the program, we simply make use of an iterative statement.

To do this, I'll make use of a do while loop.

So, we have:

Declarations

num year = 1

num copies = 100000

num price = 0.15

num total = 0

num COPIES_INCREASE = 0.04

num PRICE_INCREASE = 0.03

do:

copies = copies + copies * COPIES_INCREASE

price = price + price * PRICE_INCREASE

total = total + copies * price

output year, total

year = year + 1

while year<=10

The above do while loop enables the program to repeat the statements in the following block:

do:

----

---------

---

-

while year <=10

The loop calculates the copies & price in each year and also updates the values of the variables; so that they can be used for the nexr iteration
