Question

1. the total cost for printing x copies of a book is $200 plus $2.50 per copy. which equation represents the total cost (c)?

a. $c = 200 \times 2.50$

b. $c = 200 + 2.50x$

c. $c = 200x + 2.50$

d. $c = 200 - 2.50x$

Explanation:

Step1: Identify fixed and variable costs

Fixed cost = $200, variable cost per copy = $2.50

Step2: Form total cost equation

Total cost = fixed cost + (variable cost × number of copies)
\( C = 200 + 2.50x \)

Answer:

b. \( C = 200 + 2.50x \)
