Sarah, the yearbook editor, and Mrs. Moore, the yearbook sponsor, are reviewing costs to produce the yearbook. New yearbook design software costs $800, and it costs $15 to print each yearbook. Define the variables in the situation

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
