See below
Step-by-step explanation:
The total cost depends on:
1. Software cost
2. each yearbook cost
Variables:
Let the total cost be (y) and the cost of each yearbook be (x).
To print x yearbooks, it's going to cost 15x
Also, there is software (fixed cost) cost of 800
So total cost would be:
y = 800 + 15x
